Question 916877: Two cars pass on a straight highway while traveling in opposite directions. One car is traveling 6 miles per hour faster than the other car. After 1.5 hours the two cars are 171 miles apart. Find the speed of each car. Show work. Answer by solver91311(24713) (Show Source):
Since 1 hour is 2/3 of 1.5 hours, the two cars would be 2/3 times 171 miles apart after 1 hour. 2/3 times 171 = 114. Hence, the sum of the two cars' speeds is 114 miles per hour. If one car is going v miles per hour, then the other car, going 6 miles per hour faster is going v + 6 miles per hour. So, v + v + 6 = 114. Solve for v and then compute v + 6.
