Question

A boy travels with an average speed of 10 m s^-1 for 20 min. How much distance does he travel?

Answer 1

Average speed of boy = 10 m s^-1

Time taken = 20 min

Distance travelled = Speed × Time taken

Convert minutes into seconds

1 minute = 60 sec.

20 minutes = 20 × 60 = 1200 sec.

Distance travelled = 10 m s^-1 × 1200 sec.

= 12000 m Or 12 km
