Question

a boy travels with the speed of 10 metre per second for 30 minutes how much distance does he travels?​

Answer 1

Answer:

18000m or  18km

Explanation:

With speed = 10 m/s

Time = 30min = 30 x 60 s = 1800 s

Speed = Distance/Time

Distance = Speed*Time

Distance = 10m/s *1800s

Distance = 18000m = 18km

Answer 2

Answer: 18 km

Explanation:

Given, Speed= 10m/sec

Time= 30 minutes.

i. Time conversion:

30 min= 30×60 seconds

= 1800 seconds

ii. Distance calculation:

10 m sec^-1 × 1800 sec. (Seconds get cancelled)

=18000 m

iii. Distance conversion

18000 m to km

1 km= 1000 m

1 m= 0.001 km

Hence, 18 km
