Answer:

Jayln rode 12.4 miles/hour.

Step-by-step explanation:

The question is asking for a unit rate for the speed in miles per hour that Jayln rode her bike over her 33.48 mile ride.  Since we know that she rode a total of 33.48 miles and the total time was 2.7 hours, we can set up our ratio as 33.48/2.7 or miles/hours.  In order to find unit rate, or the number of miles per one hour, we need to divide:  33.48 ÷ 2.7 = 12.4.  So, 12.4 mph is Jaylyn's speed.
