Answer:
216miles
Step-by-step explanation:
Total gallons the tank can take = 16gallons
If his gas tank is 3/4 full, the total gallons in the tank = 3/4 * 16 = 12gallons
Since his truck averages 18 miles per gallon, we can say;
18 miles = 1 gallon
To know the distance steven will have to drive, we will write;
x = 12 gallons
Divide both expressions
18/x = 1/12
Cross multiply
x *1 = 18*12
x = 216miles
Therefore Steven can drive for 216miles without having to stop for gas
