2.64 gallons

Step-by-step explanation:

13 miles /13 minutes = 1 mile per minutes * 60 minutes/ hour = 60 miles per hour

The miles per gallon is 50 per the chart

13 miles ÷ 50 miles per gallon

Copy dot flip

13 * 1/50 gallons per mile = 13/50 gallons=.26 gallons

Now for the second leg we went 68 miles per hour

The miles per gallon is 40 per the chart

We need to find the distance

1 hour 24 minutes = 1 24/60 hours = 1.4 hours

1.4 hours * 68 mph = 95.2 miles

95.2 miles ÷ 40 miles per gallon

Copy dot flip

95.2 * 1/40 gallons per mile = 2.38 gallons

Add the number of gallons together

.26 + 2.38 = 2.64 gallons
