Question

The line graph shows the miles per gallon for a car.

Answer 1

The unit rate of gas usage is 35 miles per gallon.

Step-by-step explanation:

"Unit rate" refers to the number of miles for 1 gallon.

From the graph given,

it can be determined that, the car goes 2 miles for 70 gallons and 3 miles for 105 gallons.

To find miles per gallon, use rate formula

Rate= Given miles/ Given gallons= 2/70

Unit Rate= miles/ 1 gallon= X/1

where "X" term refers to number of miles per gallon.

By Comparing the rates we get,

2/70 =X/1

X=35 miles per gallon

Similarly,

3/105 =X/1

X=35 miles per gallon
