Question

The number of miles per gallon of gasoline that a vehicle average varies inversely as the average speed the car travels. A vehicle gets 16 miles per gallon at 53 mph. How many miles per gallon will it get at 62 mph?

Answer 1

Answer:

13.68 miles per gallon

Step-by-step explanation:

Varies inversely

mpg * speed = constant

A vehicle gets 16 miles per gallon at 53 mph

53 * 16 = 848

How many miles per gallon will it get at 62 mph?

mpg * 62 = 848

Divide both sides by 62

mpg = 848/62 = 13.6774193548

rounded

13.68 mpg
