Question

A boat can travel 200miles on 25 gallons ofgasoline. How muchgasoline will it need togo 48 miles?

Answer 1

How much a boat can travel?

We have the following information:

we want to find how gallons of gasoline will it need for 48 miles.

And we know that the boat can travel 200 miles on 25 gallons of gasoline.

We can write an equivalence with that information:

48 miles ⇄ ??

200 miles ⇄ 25 gallons

If we divide both sides of the equivalence we will have the same result:

`(48)/(200)=\frac{?\text{?}}{25}`

We want to find "??", so we multiply both sides by 25:

`\begin{gathered} 25\cdot(48)/(200)=\text{??} \\ 6=\text{??} \end{gathered}`

Answer: the boat will need 6 gallons of gasoline to travel 48 miles
