Exercise 17 Page 7

Practice makes perfect

We are given information about cars and the their gas mileage, and we are asked to find how far they can go based on that information. Let's summarize the information.

Description	Value
Miles per gallon	33
Number of gallons	46.2

According to the formula given, the product of these two numbers gives the distance traveled during a trip.

Distance traveled=Miles per gallon*Number of gallons

SubstituteII

Miles per gallon= 33, Number of gallons= 46.2

Distance traveled= 33* 46.2

Multiply

Distance traveled=1524.6

If the car gets 33 miles per gallon and uses 46.2 gallons of gasoline on a trip, then the distance traveled on the trip is 1524.6 miles.

Let's summarize the information we know again.

Description	Value
Miles per gallon	60
Number of gallons	12

According to the formula given, the product of these two numbers gives the distance the car can go on one tank of gasoline

Distance traveled=Miles per gallon*Number of gallons

SubstituteII

Miles per gallon= 60, Number of gallons= 12

Distance traveled= 60* 12

Multiply

Distance traveled=720

If a car gets 60 miles per gallon and the gasoline tank holds 12 gallons, then the car can travel 720 miles on one tank of gasoline.
