Question 268189
A car will go 3/8 of a given distance in one hour. What part will it cover in 5/8 of an hour?

Let D be the GIVEN distance and R the rate. Then since rate = distance/time we have:

R = (3/8*D)/1
R = 3/8*D

Since distance = rate*time the distance d traveled in 5/8 hour is:

d = (3/8*D)*5/8
d = 15/64*D

So the part of the distance traveled is 15/64.
