Answer 2

Hi there!

`\large\boxed{15 \text{ }min}`

Create a proportion to solve for the amount of time required to run 2 kilometers:

8 km in 60 min

2 km in x min

Express as fractions:

`(8)/(60) = (2)/(x)`

Cross multiply:

8 · x = 60 · 2

8x = 120

Divide both sides by 8 to solve for x:

8x/8 = 120/8

x = 15 minutes
