<PRE><B>Question 1172454</B>
the equation is 2/3 * t = 1/5 * d
multiply both sides of the equation by 15 to get:
10 * t = 3 * d
divide both sides of the equation by 3 to get:
10/3 * t = d
the basic form of the equation is r * t = d
r is the rate
t is the time
d is the distance.
in this equation, r = 10/3 which means the average speed is 10/3 miles per hour.
