In order to create the equation we can create a simple ratio to find out the unknown value X of how much distance can she travel with 50L of gasoline.
We know that 6L allows you to drive 72km.
That means that 50L allows you to drive X km.
Lets cross multiply, so 6 times x equal to 50 times 72.
6x=50*72 This is the equation
6x=3600
Divide both sides with 6.
6x/6 = 3600/6
x=600km is the distance she can drive with 50L of gasoline.
