Question

a train covers 's' distance at the constant speed of 30 kmph hours then it covers the same distance in opposite direction at constant speed of 45 kilometre per hour then its average velocity would be ----- kilometre per hour ​

Answer 1

Answer:

Sol: (45 + 65) ÷ 2 = 55 kmph. The total distance traveled by the motorist in these two hours = 65 + 45 = 110 km and he has taken two hours. Therefore, his average speed = 55 kmph.
