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.
