I figured out the answer for this question through guess and check, but I cannot figure out the equation I need to use to solve the problem.
Bob drove from TownA to TownB, a distance of 250 miles. He increased his speed by 10mi/hr for the 360 mile trip from TownB to TownC. If the total trip took 11 hours, what was his speed from TownA to Town B?
The answer is 50mph, but I cannot figure out how to get this without guess and check. Any help is great. Thanks.
