If the car drove 500 miles in 10 gallons of gas it means it can drive 500 miles / 10 gallons which is 50 miles per gallon.
To discover how far he could drive on 75 gallons of gas we just. havr to multiply 50 by 75 :
75×50 = 3750 miles
Awnser:
The car mileage is 50 miles per gallon
And I could drive the car for 3750 miles on 75 gallons of gas .
I hope you understood my brief explanation
