Let the usual speed of the plane = x km/hr. A plane left 30 minutes late than its scheduled time and in order to reach the destination 1500 km away in time, it had to increase its speed by 100 km/h from the usual speed. Given distance d = 1500km and the speed increase by s= 250km/h also that the plane left 30 minutes later than the scheduled time.
A plane left 30 minutes late than its scheduled time and
It had to increase its speed by 100 km/h from the usual speed.
Let the usual speed of the plane be x km/hr.
A plane left 30 minutes later than the scheduled time and in order to reach the destination 1500 km away in time, it had to increase the speed by 250 km/hr from the usual speed. A plane left 30 minutes late than its scheduled time and in order to reach the destination 1500 km away in time, it had to increase its speed by 100 km/h from the usual speed. Distance covered by the plane = 1500 km let the usual speed be s km/hr let the usual time taken be t hr. A plane left 30 minutes later than the scheduled time and in order to reach the destination 1500km away in time, it has to increase the speed by 250km/hr from the usual speed.
Asked sep 27, 2018 in mathematics by minu (46.2k points) a plane left 30 minutes late than its scheduled time and in order to reach of destination 1500 km away in time.
A plane left 30 min later than the scheduled time and in order to reach its destination 1500 km away in time, it has to increase its speed by 250km/hr from its usual speed. A plane left 30 minutes late than its scheduled time and in order to reach the destination 1500 km away in time, it had to increase its speed by 100 km/h from the usual speed. The plane left 30 minutes late and reached on time. So, according to the question.
This is the solution of question from rd sharma book of class 10 chapter quadratic equations this question is also available in r s aggarwal book of class 10.
∴ speed in this instance = (s + 100) km/hr. Time take to reach the destination at the usual speed, t 1 = 1500 x hr. Increased speed of the plane = ( x + 100) km/hr. A plane left 30 minutes later then the scheduled time and in order to reach the destination 1500 km away in time, it has to increase the speed by 250 km/hr from the usual speed.
A plane left 30 minutes later than the scheduled time and in order to reach the desination, 1500km away in time.
Let the usual speed of the plane = x km/hr. Let the speed be x km/h to cover a distance of 1500 km 30 minutes = 30/60 hours = 1/2 hours , where t is the time, d is the distance and s is the speed of the plane. A) 250 kmph b) 500 kmph c) 750 kmph d) 1000 kmph e) 1200 kmph
A plane left 30 minutes late than its scheduled time and in order to reach the destination 1500 km away in time, it had to increase its speed by 100 k.
Distance covered by the plane = 1500 km let the usual speed be s km/hr let the usual time taken be t hr. Time take to reach the destination at the increased speed, t 2 = 1500 x + 100 h r. A plane left 30 minutes late than the schedule time and in order to reach its destination 1500 km away in time,it has to increase its speed by 100 km/h from its usual speed.find its usual speed. An aeroplane left 30 minutes later than it schedule time and in order to reach its destination 1500 km away in time, it had to increase its speed by 250 km/hr from its usual speed.

∴ speed in this instance = (s + 100) km/hr. A plane left 30 minutes later than the scheduled time and in order to reach its destination 1500 km away in time, it has to increase its speed by 250. Distance to the destination = 1500 km increased speed = 100 km/hr. A plane left 30 minutes late than its scheduled time and in order to reach the destination 1500 km away in time, it had to increase the speed by 250 km/h from the usual speed.
And in order to reach its destination 1500 km away in time, it has to increase its speed by 250 km/hour from its usual speed.
===== if you need a complete and detailed solution, let me know!! The plane left 30 minutes late and reached on time. An aeroplane left 30 minutes later than its scheduled time; Let the usual speed of the plane be x km/hr.
Asked in aieee (12 years ago) solved c.t.narayanan read solution (3)
We use the formula for determining time in terms of distance and speed which is, t = d s. A plane left 30 minutes late than its scheduled time and in order to reach the destination 1500 km away in time, it had to increase its speed by 100 km/h from the usual speed. A plane left half an hour later than the scheduled time and in order to reach its destination 1500 kilometers away in time, it had to increase its speed by 33.33 percent over its usual speed. It has to increase the speed by 250km/h from the usual seed.
