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.

<h3>Answer: A) 52 square inches</h3>
==========================================================
Explanation:
a = 8, b = 13, and c = 15 are the sides of the triangle
s = (a+b+c)/2 = (8+13+15)/2 = 18 is the semi-perimeter, aka half the perimeter.
Those values are then plugged into Heron's Formula below
The triangular plaque has an area of approximately 52 square inches.
