Matt needs to swim 8 meters in 25 seconds yo qualify as a state swimer. Which unit rate describes the speed Matt needs to swim​
fiasKO [112]

Answer:

Option D, 0.32 meters per second

Step-by-step explanation:

<u>Step 1:  Find the unit rate at which Matt needs to swim</u>

Make an equation to represent the scenario.

<em>25m = 8</em>

<u>Step 2:  Solve for m by dividing both sides by 25</u>

25m / 25 = 8 / 25

<em>m = 0.32</em>

<u>Step 3:  Check</u>

To check, you can multiply the number of second, 25, by the meters per second to see if you get the total meters, 8.

0.32 * 25

<em>8</em>

So, the answer is correct :)

<u><em>0.32 means that Matt needs to swim 0.32 meters per second to qualify as a state swimmer.</em></u>

Answer:  Option D, 0.32 meters per second
