The distance traveled is 20 miles.

Work Step by Step

This is the formula we will use to relate distance d, rate r, and time t. $d=rt$ Since we are given a rate in miles per hour, we must convert the time to hours. $15$ min = $0.25$ hrs Plug in the information to the distance formula. $d=80\frac{mi}{hr}*0.25hr$ Multiply. $d=20mi$
