Question

A boy travels with an average speed of 10 m/s for 20 minutes. How much distance does he travel?

Answer 1

Answer:

Average speed of boy = 10 ms−1

Time taken = 20 min 

Using, Distance travelled = Speed × Time taken

Convert minutes into seconds

1 minute = 60 sec.

20 minutes = 20×60=1200 sec.

Distance travelled =10 ms−1×1200 sec 

.=12000 m  or 12 km
