Sam walks 2 km in 30 minutes. How much time will he take to cover 400m?

6 minutes

Explanation:

✓Sam walks 2 km in 30 minutes.

2 km = 30 minutes. (1)

How much time will he take to cover 400m?

But 400m= 0.4km

Let the time will he take to cover

0.4 km= x(2)

Then we have

2 km = 30 minutes.

0.4km= x

Then cross multiply, we have

2km × X = (30×0.4)

X= (30×0.4)/2

X= 12/2= 6 minutes
