If a truck travels 301 miles on 19 gallons of gas how many miles per gallon does it average (to the nearest tenth)?

ANSWER:  

On an average, the truck traveled approximately 15.8 miles per each gallon.

SOLUTION:

Given, a truck travels 301 miles on the gas of 19 gallons.

Then, total distance traveled = 301 miles

Total number of gallons of gas used = 19 gallons

We need to find miles traveled per gallon on an average.

Now, miles traveled per gallon =

Miles traveled per gallon = = 15.842

Rounding to nearest tenth place. Here “8” is in the tenth place. The number which is to right of 8 is 4 which is less than 5. So the numbers to right of 8 disappears and we get solution as 15.8

On an average, the truck travelled approximately 15.8 miles per each gallon.
