William runs 5 meters in 20 steps. How many kilometers will he run after taking 1000 steps?

1 kilometer = 1000 meters

First, lets find the amount of meters that he runs. Then, we will transform it into kilometers.

Lets set up a proportion.

5/20 = x/1000

Cross multiply ⇒ 5*1000 = x * 20

5000 = 20x

5000/20 = x x = 250

He runs 250 meters, but how many kilometers can he run?

1 kilometer = 1000 meters

0.25 kilometers = 250 meters

Answer: William runs 0.25 kilometers in 1000 steps.
