Tony drives his car He drives the first 13 miles in 13 minutes, he then drives at an average speed of 68mph for 1 hour 24 minutes. How much petrol does he use

2.64 gallons

Step-by-step explanation:

Using the information in the table to find out how much petrol he uses. Average speed Miles travelled per gallon 65 mph or less More than 65 mph 50 40 mph stands for miles per hour

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

13 × 1/50 gallons per mile = 13/50 gallons = 0.26 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

95.2 × 1/40 gallons per mile = 2.38 gallons

Add the number of gallons together

0.26 + 2.38 = 2.64 gallons
