Question

If your car gets 30.3 mi/gal, how many gallons of gasoline would you use if you drove 506.3 miles? 1 mile = 5280 ft (exactly) Include one decimal place in your answer.

Answer 1

Answer : The number of gallons of gasoline needed are 16.7 gallons

Explanation :

As we are given that the car traveled 30.3 mi/gal. Now we have to determine the number of gallons of gasoline needed in 506.03 miles.

As, 30.3 miles car traveled in = 1 gallon

and, 1 miles car traveled in = $\frac{1\text{ mile}}{30.3\text{mile}}\times 1 \text{ gallon}$

So, 506.3 miles car traveled in = $\frac{506.3\text{ mile}}{30.3\text{mile}}\times 1 \text{ gallon}$

                                                    = 16.7 gallons

Therefore, the number of gallons of gasoline needed are 16.7 gallons

Answer 2

Answer: 16.7 gallon

Explanation:

Given: The car can drive 30.3 miles when 1 gallon of gasoline is used.

Distance covered = 506.3 miles

Thus for 30.3 miles, the amount of gasoline used= 1 gallon

For 506.3 miles, the amount of gasoline used=$\frac{1}{30.3}\times 506.3=16.7gallon$

Thus the amount of gasoline used is 16.7 gallons.
