A bus can cover a distance of 6 miles in 1 gallon of gas. The cost of gas is $4 per gallon.
What will be the cost of gas used in driving the bus for 96 miles?
6 miles 96 miles
________ = _________
1 gallon x gallons
cross multiply to figure out how many gallons you used in 96 miles, and then multiply by $4 to get the cost.
64
An example of a ratio is Dollars:Miles.
The unit rate is helpful when reasoning about ratios.
Write the first ratio that is given as a fraction:
6miles$4
Reduce it to simplest form:
6miles÷4$4÷4=1.5miles$1
Use the simplified fraction to set up a proportion to solve for the missing value:
1.5miles×64$1×64=96miles$64
Use inverse operations:
96÷1.5=64
Therefore, the cost of gas that will be used to drive the bus for 96 miles is $64.

To find the cost of gas used in driving the bus for 96 miles, we need to determine how many gallons of gas will be consumed.
First, let's calculate the number of gallons required to cover 96 miles. We know that the bus covers 6 miles with 1 gallon of gas, so we can set up a proportion:
6 miles / 1 gallon = 96 miles / x gallons
To solve for x (the number of gallons required for 96 miles), we can cross multiply:
6x = 96
Now divide both sides by 6 to isolate x:
x = 96 / 6
x = 16
So, the bus will require 16 gallons of gas to travel 96 miles.
Next, we need to calculate the cost of 16 gallons of gas. Given that the cost of gas is $4 per gallon, we can multiply the number of gallons (16) by the cost per gallon ($4):
16 gallons * $4/gallon = $64
Therefore, the cost of gas used in driving the bus for 96 miles would be $64.
