Brian ran a 5-kilometer race in 40 minutes. how far did he run in 18 minutes? write your answer as a decimal and do not round.

Answer 1

To find the distance Brian ran in 18 minutes, we can use the ratio:

Distance in 18 minutes / Distance in 40 minutes = Time in 18 minutes / Time in 40 minutes

Let's solve for the distance in 18 minutes:

(Distance in 18 minutes) / 5 km = 18 minutes / 40 minutes

Cross-multiplying, we get:

(Distance in 18 minutes) = (18 minutes / 40 minutes) * 5 km

Simplifying:

(Distance in 18 minutes) = (9/20) * 5 km

Calculating the result:

(Distance in 18 minutes) = 2.25 km

Therefore, Brian ran 2.25 kilometers in 18 minutes.
