A plane left 30 minutes later than the schedule time and in order to reach its destination 1500 km away in time, it has to increase its speed by 250 km/hr from its 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. 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 in order to reach the destination 1500 km away in time it had to increase.
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.
=> 2 (37500) = x (x + 250) => 75000 = x² + 250x. Closed nov 25, 2020 by ishti. A plane left 30 minutes or 1/2 hours later than the scheduled time. A plane left 30 minutes later than the schedule time and in order to reach its destination 1500 km away in time, it has to increase its speed by 250.
Increased speed of the plane = ( x + 100) km/hr.
So, according to the question. Let the usual speed of the plane = x km/hr. Time = distance / speed. Find its usual speed a plane left 30 min later than the scheduled time and in order to reach the destination 1500km away in time it has to increase the speed by 250km/h from the usual speed.
Asked nov 3, 2017 in class x maths by akansha expert (7.8k points) a plane left 30 minutes later than the scheduled time and in order to reach the desination, 1500km away in time.
Distance covered by the plane = 1500 km let the usual speed be s km/hr let the usual time taken be t hr. ∴ speed in this instance = (s + 100) km/hr. We use the formula for determining time in terms of distance and speed which is, t = d s. Solution (by examveda team) by increasing the speed by 33.33%, it would be able to reduce the time taken for traveling by 25%.
===== if you need a complete and detailed solution, let me know!!
It had to increase its speed by 100 km/h from the usual speed. The plane left 30 minutes late and reached on time. An aeroplane left 30 minutes later than its scheduled time; But since this is able to overcome the time delay of 30 minutes, 30 minutes must be equivalent to 25% of the time originally taken.
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 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. , where t is the time, d is the distance and s is the speed of the plane. 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.
Hence, the new speed would be.
Km/h you can do the check!! Time take to reach the destination at the usual speed, t 1 = 1500 x hr. Let the usual speed of the plane = x km/hr. Hence, the original time must have been 2 hours and the original speed would be 750 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 km/h from the usual speed.
Distance to the destination = 1500 km increased speed = 100 km/hr. 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. It has to increase the speed by 250km/h from the usual seed. Let the usual speed of the plane be 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 k.
