Question

A train moving at a speed of 75 km/ hr cover a certain distance in 4.8 hours. what should be. the train to cover the same distance in 3 hours​

Answer 1

Answer:

DISTANCE = SPEED X TIME.

AS THE DISTANCE IS SAME THROUGHOUT. SPEED = 360 / 3 = 120 KMPH.

SPEED OF THE TRAIN SHOULD BE 120 KMPH TO COVER THE SAME DISTANCE IN 3 HOURS

Answer 2

Speed = 75 km/hr

Time = 4.8 hours

therefore, distance = speed × time = 75 × 4.8 = 360 km

therefore, speed = d/t = 360/3 = 120 km/hr

Hope it helps :)
