Question

A boy is running on a straight road he runs 500 metres towards north in 2 minutes and 10 seconds and then turns back and runs 500 in 3 minutes and 13 seconds find the average velocity for journey

Answer 1

Explanation:

Total distance = 500 m

Total time = 130 + 193 s = 323 s

So,

$average \: velocity \: = \frac{total \: distance \: }{total \: time \: } \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{500}{323} m/s = 1.54m/s$
