An automobile uses 8 gallons in traveling 120 miles at that rate how many gallons will be used in 360 miles?
120 / 8 = 15 mpg
360 / 15 = _______ gallons
To calculate the number of gallons used in traveling 360 miles at the same rate, you can set up a proportion using the information provided.
The proportion can be set up as follows:
8 gallons : 120 miles = x gallons : 360 miles
To find the value of x (the unknown number of gallons used in traveling 360 miles), you need to solve this proportion.
To solve the proportion, you can cross-multiply and then divide:
8 * 360 = 120 * x
2880 = 120 * x
Next, divide both sides of the equation by 120:
2880 / 120 = x
x = 24
Therefore, in traveling 360 miles at the same rate, the automobile will use 24 gallons.
