Number of gallons of gas. Miles driven 0 0 2 62 4 124 10 310 How many gallons are used when the car has been driven 18 miles

Answer 1

558 gallons are used when the car has been driven 18 miles.

Step-by-step explanation:

From the given data, it can be determined that :

• The number of gallons for 2 miles = 62 gallons
• The number of gallons for 4 miles = 124 gallons
• The number of gallons for 10 miles = 310 gallons

Let, the number of gallons for 18 miles = 'x' gallons

To find x :

compare the given data with the unknown data,

62 gallons / 2 miles = x gallons / 18 miles

keep x alone on one side,

x = (62×18) / 2

x = 31×18

x = 558 gallons

Therefore, 558 gallons are used to drive 18 miles.
