Martin runs a 5 kilometer race in 25 minutes. What is his unit rate?

Does the question want the unit rate for hours? such as km/h? or km/minute?

If they want the unit rate for minutes, then it is 0.2 kilometers every 1 minute.

If they are asking for the unit rate for hours, it is 12 kilometers for every 1 hour.

[ 60/25 ] x 5 km/h = 12 km/h
