Question

the track on which jane races is 1/4 of a mile long. How many laps must she drive in a race that is 50 miles long

Answer 1

200laps

Given information:

The track = 1/4 miles long

We are to find the number of laps in a race that is 50 miles long.

In 1 mile, we have 4 laps

in 1/4 mile, we would have:

`=\text{ }\frac{1\text{mile}}{4}*\frac{4\text{laps}}{1\text{mile}}=\text{ 1 lap}`

In 50miles, we would have:

`\begin{gathered} (1)/(4)mile=1\text{ lap} \\ 50\text{mile = 50}*1*(4)/(1) \\ =\text{ 200laps} \end{gathered}`

The number of laps that she must drive in a race that is 50 miles long = 200laps.
