Question

Jacqueline drove 72 km on 6 L of gasoline. Which of the following equations can be used to find how far she can travel on a full tank of 50 L?

Answer 1

600 miles but how would you write that..

Answer 2

If Jacqueline drove 72 km on 6 L of gasoline, she should be able to travel 600 miles on a full 50 L tank. Divide 50 L (full tank) by 6 L (known variable). Multiply 8.33 * 72 (known variable) to get the final answer of 600 miles.

Answer 3

you have a ratio of 72/6. if you simplify that you will get a ratio of 12/1.
now you only have to multiply 12 times 50 to find the answer.
that is in fact 600
\[\frac{ 72 }{ 6 } \frac{ x }{ 50 }\]
after the simplification you get
\[\frac{ 12 }{ 1}\frac{ x }{ 50}\]

now you cross multiply to get the answer.
