|
Answer» f the train = 75 km/hr Time = 4.8 HOURS Time = 3 hours SPEED of the train ?Formulae used :- Solution :- Consider the case - 1 GIVEN :- Speed of the train = 75 km/hr Time = 4.8 hours So, Using the formula Substitute the values Hence, Distance = 360 kilometers Similarly , Consider case - 2 Given :- Time = 3 hours However, He also mentioned that ;The distance in both cases is same .So, Distance = 360 kilometers We need to find the speed of the train to travel that distance in 3 hours Hence, using the formula , So, The train should travel at a speed of 120 km/hr to COVER the distance in 3 hours . |
