<human>:  Sophia is thinking of taking a road trip in her car, and would like to know how far she can drive on a single tank of gas. She has traveled 100 miles since last filling her tank, and she needed to put in 4 gallons of gas to fill it up again. The owner's manual for her car says that her tank holds 12 gallons of gas. How many miles can Sophia drive on a single tank of gas?
<bot>: How many miles does Sophia get per gallon? ** To find miles per gallon divide 100 miles / 4 gallons = <<100/4=25>>25 miles per gallon
How many miles can Sophia drive on a single tank? ** To find how far Olivia can go on a single tank, multiply 25 miles per gallon x 12 gallons = <<25*12=300>>300 miles
#### 300
