Question

A boy covers a distance of 2.5 km in 15 minutes and the next 3 km in 18 minutes. What is the average speed of the boy?​

Answer 1

Speed = Distance/Time

2.5 km + 3 km = 5.5 km

5.5 km = 550 m

15 min + 18 min = 33 min

33 min = 1980 sec

Speed = 550 / 1980

Speed = 275 m/ 99s

( 2.77 m/s )
