20 gallon tank
14 mpg
550 miles to drive
How much would it cost to drive 550 miles with a 20 gallon gas tank and getting 14 mpg?
Answer provided by our tutors
The "cost" is ambiguous because no price for gas is specified, but we can think of "cost" in "how many tanks of gas" would be required. So "miles per gallon" divided into "miles" (550/14) yields "how many gallons" and then divided by "how many gallons in a tank" yields "how many full tanks are required":
(550/14)/20
1.96
So it would take approximately 2 full tanks of gas.
