When you say "at the same ratio", you mean that you consume the same amount of gas for the same amount of miles.
We know that everytime you drive 75 miles, you use 3 gallons of gas.
Since 12 gallons of gas is four times 3 gallons of gas, if the ratio remains the same, you can drive four times the distance:
You drive 75 miles, and use 3 gallons.
You drive 75 more miles (so you are at  miles) and use 3 more gallons, so you use
 miles) and use 3 more gallons, so you use  gallons.
 gallons.
You drive 75 more miles (so you are at  miles) and use 3 more gallons, so you use
 miles) and use 3 more gallons, so you use  gallons.
 gallons.
You drive 75 more miles (so you are at  miles) and use 3 more gallons, so you use
 miles) and use 3 more gallons, so you use  gallons, and you're done.
 gallons, and you're done.

Take DEBC a parralelogram
Parralel sides are DE and BC
THEREFORE,
1/2*(a+b)*h
1/2*(6+15)*h
1/2*(21)*h=0
10.5*h=0
h=-10.5
