It will take Chad 12 hours to drive 672 miles and he will need 24 gallons of gasoline
How to calculate many hours will it take Chad to drive 672 miles?
Given that: Chad is planning a 672–mile road trip
Chad’s car can travel 308 miles with 11 gallons of gas. We can use this information to calculate the miles 1 gallon can cover. Thus:
Number of miles per gallon = 308/11 = 28 miles per gallon
Also, Chad plans to drive 168 miles every 3 hours. We can use this information to calculate Chad's speed. Thus:
Speed = 168/3 = 56 miles per hour
To determine how many hours it will take Chad to drive 672 miles:
Speed = distance/time
=> time = distance/speed
Speed = 56 miles per hour and distance = 672 miles
time = 672/56 = 12 hours
Number of gallons = distance / Number of miles per gallon
Number of gallons = 672/28 = 24 gallons
Therefore, it will take Chad 12 hours to drive 672 miles and he will need 24 gallons of gasoline
