Martin can run a kilometer in 7 minutes. If he keeps at this pace how many minutes will it take him to run a 5k race?

It would be 35 because if it take 7 minutes to run a kilometer you would have to multiply 7 • 5

5=x

7•5 = 35 minutes

35 minutes

Step-by-step explanation:

Martin can run a kilometer in 7 minutes. If he keeps at this pace how many minutes will it take him to run a 5k race?

To solve this, we simply need to use proportion.

Let x represent the number of minutes that will take Martin to run a 5 kilometer race

1 kilometer = 7 minutes

5 kilometer = x

cross-multiply

1 * x = 7 * 5

x = 35 minutes

Therefore, it will take Martin 35 minutes to run a 5 kilometer race.
