Question

Josiah traveled 79.5 miles on 3 gallons of gasoline. At this rate, how many gallons of gasoline would he need to travel 265 miles?
options:

11 gallons

10 gallons

14 gallons

26.5 gallons

Answer 1

Josiah would need 10 gallons to travel 265 miles.

First we divide 79.5 by 3 to find out how many gallons are needed for one mile.

79.5/3=26.5

For one mile we need 26.5 gallons of gas.

Now we will divide 265 by 26.5 to find the answer to the problem.

265/26.5=10

Josiah will need 10 gallons of gas to travel 265 miles

Answer 2

Answer:

Option B. 10 gallons.

Step-by-step explanation:

Josiah traveled 79.5 miles on 3 gallons of gasoline.

We have to calculate the amount of gasoline he would need to travel 265 miles.

∵ Josiah can travel on 3 gallon of gasoline = 79.5 miles

∴ He can travel on 1 gallon of gasoline = $\frac{79.5}{3}$

                                                                =  26.5 miles

∴ He would need the amount of gasoline to travel 265 miles = $\frac{265}{26.5}$

                                                                 = 10 gallons

He would need 10 gallons of gasoline to travel 265 miles.
