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 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. 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 30 minutes later than the scheduled time and in order to reach the desination, 1500km away in time. 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.
So, according to the question.
Closed nov 25, 2020 by ishti. 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. According to the question, plane left 30min later than the scheduled time. We use the formula for determining time in terms of distance and speed which is, t = d s.
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.
Let the usual time taken be t hr. ∴ speed in this instance =. Let the usual speed of the plane = x km/hr. Let the usual speed of the plane be x 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.
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. , where t is the time, d is the distance and s is the speed of the plane. 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.
The plane left 30 minutes late and reached on time.
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\. 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. ∴ speed in this instance = (s + 100) km/hr. Speed increased by 100 km/hr.
It had to increase its speed by 100 km/h from the usual speed.
Let the usual speed be s km/hr. 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 minutes late than its scheduled time and in order to reach the destination1500 km away in time, it had to increase the speed by 250 km/h from. 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.
It has to increase the speed by 250km/h from the usual seed. An aeroplane left 30 minutes later than its scheduled time;
