Question

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

Answer 1

speed = distance / time. With speed = 10 m/s and time = 20 x 60 s, the distance travelled = 10 x (20 x 60) m = 12 000 m or 12 km.

It might seem like a large distance but remember than 70 mph = 30 m/s (close enough for a decent approximation) so 10 m/s = 23.33 mph. And 20 minutes = 1 /3 of an hour.

So distance = 23.33 x (1/3) = 7.78 miles.

Converting this to km to see if we’re in the right ball-park, multiply by 1.61.

Then distance = 7.78 x 1.61 = 12.52 km.

Answer 2

Answer:

speed = distance / time. With speed = 10 m/s and time = 20 x 60 s, the distance travelled = 10 x (20 x 60) m = 12 000 m or 12 km.
