On five successive days, a motorcyclist listed his mileage as follows: 135, 162, 98, 117, 216. If his motorcycle averages 14 miles for each gallon of gas used, how many gallons of gas did he use during these five days?

Explanation

First, find the total mileage; 135+162 + 98 + 117 + 216 = 728 miles. Divide the total mileage (728) by the number of miles covered for each gallon of gas used (14) to find the number of gallons of gas needed;\( 728 \div 14=52\)gallons.
