Question

You go for a half day hike. In 4 hours, you hike 10 miles. Which is a unit rate that describes your journey?

A- 5 miles per hour
B- 2.5 miles per hour
C- 4/10 (<--fraction) miles per hour
D- 10 miles per hour <--- mum thinks this is 'answer' >,< -(???)

Answer 1

The answer would be B) 2.5 miles per hour.
Number of miles travelled in an hour = 10/4 =2.5
Sorry to say but I am pretty sure D) isn't the answer.

Answer 2

B-2.5mph You divide 10 (how far you went) by 4 (the amount of time it took you) which gives you 2.5 (the amount of time it takes you to walk 1 mile) To check: It takes you 2.5 hours to walk 1 mile so multipling 2.5 by 4 tells you how far you walked in 4 hours
