Question

To start a road trip, a car encountered a traffic jam, traveling a total of m miles after the first hour and a total of m2 miles after the second hour. If the ratio of the distance traveled during the first hour to the distance traveled during the second hour is 1 to 7, how far had the car traveled after 2 hours?

Answer 1

56 miles, The car traveled m miles during the first hour and m squared miles during the second hour. The ratio m/m squared = 1/7 and cross multiplying yields m squared = 7m, so m=7. This means that the total distance traveled was 7+7squared = 56 miles
