A car travels 200 miles at 55 miles per hour at 22 miles per gal. How many gallons of gasoline would it use in 5 hours?
my answer is 12.5 gals.
correct
this question makes absolutely no sense
To calculate the number of gallons of gasoline the car would use in 5 hours, we need to first calculate the total distance traveled in 5 hours and then divide it by the car's fuel efficiency. Here's how you can do it step by step:
1. Calculate the distance traveled in 5 hours:
To find the distance, we can use the formula distance = speed × time. In this case, the car's speed is given as 55 miles per hour, and the time is 5 hours. Therefore, the distance traveled in 5 hours is 55 miles/hour × 5 hours = 275 miles.
2. Calculate the fuel consumption:
The car's fuel efficiency is given as 22 miles per gallon. Therefore, the car would consume 1 gallon of gasoline for every 22 miles traveled.
3. Calculate the number of gallons of gasoline used in 5 hours:
Now that we know the distance traveled in 5 hours is 275 miles, we can divide it by the car's fuel efficiency to find the number of gallons of gasoline used.
275 miles ÷ 22 miles/gallon = 12.5 gallons
So, the correct answer is indeed 12.5 gallons of gasoline.
