Question

The winner of the New York marathon ran the 8 kilometer event in 24 mins. What is runners unit rate? Plz explain

Answer 1

Answer: $\dfrac{1}{3}$ km per minute

Step-by-step explanation:

Given : The winner of the New York marathon ran the 8 kilometer event in 24 mins.

Then, the  runners unit rate is given by :_

$\text{Runner's unit rate}=\dfrac{\text{Distance}}{\text{Time}}$

i.e. $\text{Runner's unit rate}=\dfrac{8}{24}=\dfrac{1}{3}$

Hence, the runners unit rate = $\dfrac{1}{3}$ km per minute.

Answer 2

A unit rate is when a rate is expressed by having 1 as the second number...

So for your problem you would want to find out how many minutes it took the runner to run 1 kilometer 

To obtain the unit rate for your problem you will need to divide the numerator (24) by the denominator (8)

when you divide 24 by 8 the final answer is 3

so the unit rate is.....

the runner will run 1 kilometer in 3 minutes

also expressed as 1:3

i'm guessing this is what you wanted?
I hope this helps!
