Question

Terry skated 2 miles in 1/2 hour. Which of the following represents the unit rate that terry skates?

Answer 1

The unit rate is 1 mile per hour

Answer 2

Hello!

The unit rate is something out of one. This is out of 1/2 hour. To get it to one, we multiply both sides by 2.

2:0.5=4:1

Therefore, the ratio 4:1 or 4 miles every hour is our unit rate.

I hope this helps!
