Question 916877
<font face="Times New Roman" size="+2">


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.
