Question

A boat can travel 412 miles on 103 gallons of gasoline. How much gasoline will it need to go 184 miles?

Answer 1

Hey there! I'm happy to help!

Let's set this up as a proportion (2 equal ratios).

$\frac{miles}{gallons} =\frac{412}{103} =\frac{184}{g}$

If you multiply the diagonal numbers, their products will be equal. (412×g=103×184). This is called cross multiplying. Now we can solve for g.

412g=18952

Divide both sides by 412.

g=46

Therefore, the boat will need 46 gallons of gasoline to go 184 miles.

Have a wonderful day! :D
