Question

A boy travels with a speed of 10 ms1 for 30 minute . How much distance does he travel​

Answer 1

Answer: 18000 m or 18 km

Explanation:

1 minute = 60 seconds

∴ 30 minutes = 60 x 30 seconds

                      = 1800 seconds

∵The boy is travelling at 10 m$s^{-1}$, total distance covered by him = 1800 x 10 m

                                                                                                           = 18000 m

If you need the answer in kilometer :

∵ 1000 m = 1 km

∴ 18000 m = 18000 ÷ 1000 km

                 = 18 km
