Let x be the slower rate (in miles per hour); then the faster rate is (x+5) mph.
Write an equation for the total separating distance
8*x + 8*(x+5) = 264.
Simplify step by step
8x + 8x + 40 = 264
16x = 264 - 40
16x = 224
x = 224/16 = 14.
ANSWER. The slower rate was 14 mph; the faster rate was 14 + 5 = 19 mph.
CHECK. 8*14 + 8*19 = 264 miles, the total separating distance. ! Correct !
Solved.
