you are on a 750 mile trip by car . ur car used seven gallons of gas to travel the first 210 miles of the trip. how much more gas will u need to make it the rest of the way at the same rate ? show work

Respuesta :

Answer:

A total of 18 gallons of more gas

Step-by-step explanation:

7 gallons = 210 miles

750-210= 540

210*2 =420 miles       7*2=14 gallons

210/2= 105                  7/2=3.5 gallons

525 miles                       17.5 miles

210/14= 15                      7/14=.5 gallons

540 miles                    18 gallons
