Distance covered by the plane = 1500 km. 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. 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.
Solution (by examveda team) by increasing the speed by 33.33%, it would be able to reduce the time taken for traveling by 25%.
Distance to the destination = 1500 km increased speed = 100 km/hr.
The plane left 30 minutes late and reached on time. Hence, the new speed would be. 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. ∴ speed in this instance =.
Speed increased by 100 km/hr.
An aeroplane left 30 minutes later than its scheduled time; It had to increase its speed by 100 km/h from the usual speed. So, according to the question. Closed nov 25, 2020 by ishti.
, where t is the time, d is the distance and s is the speed of the plane.
A plane left 30 minutes later than the scheduled time in order to reach its destination, 1500 km away it has to increase its speed by 250km/hr than his 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. 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. Let the usual speed be s km/hr.
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.
Let the usual speed of the plane be x km/hr. Increased speed of the plane = ( x + 100) km/hr. 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. Let the usual time taken be t 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 km/hr from its usual speed.
Time take to reach the destination at the increased speed, t 2 = 1500 x + 100 h r. 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.
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. Answer of a plane left 30 minutes later than the scheduled time and in order to reach its destination talk to our counsellor: 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. Hence, the original time must have been 2 hours and the original speed would be 750 kmph.
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.
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. It has to increase the speed by 250km/h from the usual seed. A plane left 30 minutes later than the scheduled time and in order to reach the desination, 1500km away in time.
