Using the relation between velocity, distance and time, it is found that t = 3 hours.
<h3>What is the 
relation between velocity, distance and time?</h3>
Velocity is <u>distance divided by time</u>, hence:

For this problem, the parameters are given as follows:
d = 15 miles, v = 5 mph
Hence the time in hours is found as follows:


5t = 15
t = 15/5
t = 3 hours.
