Question

A train travels 100 km to reach town A in one hour and 15 min. The train stops at station A for 45 minutes. Then it travels 150 km to station B in 2 hours. What is the average velocity of the train?
Average velocity=displacement/time

Answer 1

Answer: 62.5 km/hour is the average velocity of the train.

Explanation:

Displacement of the train = 100 km + 150 km = 250 km

Total time train took =1 hour 15 min+ 45 min + 2 hours = 240 min = 4 hours

Average velocity=$\frac{Displacement}{time}=\frac{250 km}{4 hour}=62.5 km/h$

62.5 km/hour is the average velocity of the train.
