Amount of gas required to travel
is
.
Further explanation:
The word problems can be solved from the unitary method.
The unitary method is a method in which we have to first find the value of a single unit then further find the required value by multiplying the single unit value.
Given:
A van travelled
on
of gas.
Calculation:
Step 1:
First we have to find the number of gallons in one mile.
It is given that the number of gallons needed to travel
is equal to
.
Use the unitary method to calculate the number of gallons in one mile.
It is calculated as follows:
Step 2:
Now, we have to calculate the number of gallons needed to travel in
.
Use the unitary method to calculate the required value by multiplying the single unit value.
The number of gallons in one mile is
.
Therefore, the number of gallons in
is calculated as follow:
Thus, the Van requires
of gas to travel
.
