Question 848325
time taken by plane A for certain distance is 3.5 and Plane B takes 2.5 to cover the same distance.
Let the speed of Plane A be x then plane B is x+300
Distance = speed* time
x*3.5 = 2.5(x+300)
3.5x = 2.5x + 750
x = 750
Speed of Plane A is 750 km/hr and speed of Plane B is 750+300 = 1050 km/hr
