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

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!

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
