for 20 min. How much distance does he travel ?
12 km​

Answer 1

Answer:

12km

Explanation:

distance=speed*time

=10ms^-1*20min

=10×1200sec

=12000m

=12km

Answer 2

You already gave the answer so explained here :

Speed of boy is 10 metre per second

Time he traveled is 20 minutes

The distance he traveled is not mentioned

We know that ,

Speed = Distance/ Time Taken to travel the distance

So According To The Problem

We will put the values we know:

10m/s = Distance / 20 minutes

Distance Travelled = 10m/s X 20 minutes

Distance Travelled = 12000m

Distance Travelled = 12km

So here is explanation might be helpful for someone.
