Question

A school has a hurdle track that is 1/5 of a mile long. They are considering extending the track to be 1/4 of a mile long. The committee wants to know the unit rate of length in the longer track per mile of length in the shorter track to make sure they have enough hurdles for the longer track. What is the unit rate?

Answer 1

Answer:   4/5

Step-by-step explanation:

Here,  The hurdle track that is 1/5 of a mile long.

And, After extending the track, the length of the hurdle track = 1/4 of a mile

Therefore, the unit rate of length in the longer track per mile of length in the shorter track = the initial length of the hurdle track / the final length of the hurdel track

= $\frac{1/5}{1/4}$

= $\frac{4}{5}$

Answer 2

Answer: 1 1/4

Step-by-step explanation:

1/4 divided by 1/5 = 5/4
