Unit 2 lesson 9

Question

d. Write an equation that makes it easier to find the the amount of gas left in the tank, xx, if we know the car has traveled ddmiles.

x=x=    

  

Answer 1

If m = the miles per gallon and t = the capacity of the gas tank in gallons:

x = t-d/m

For example, if t = 16 gallons and the mileage of the vehicle is 30 miles per gallon.

x = 16-d/30
