Question

A train covers one-third of total distance with speed of 10 km/h, the second one-third distance
with speed of 20 km/h and last one-third of the distance with speed of 60 km/h. What is the
average speed of the train ?​

Answer 1

Answer:

33.33 km/hr (approx)

Explanation:

Speed of the first one-third = 10km/h

Speed of the second one-third = 20km/h

Speed of the third one-third = 60km/h

Therefore, average speed = (10 + 30 + 60) / 3 hrs

= 100/3 km/hr

= 33.33km/hr (approx)

Hope this is the correct answer. And, I hope that it helps :)
