vlada-n [284]

The difference between both unit rates rounded off to the nearest tenth is: 0.4 meters per second

Step-by-step explanation:

We have to calculate his unit rate for both type of races

So,

<u>Unit rate for 400m race:</u>

Distance = 400m

Time = 43 sec

Unit\ rate = U_1= \frac{Distance}{Time}\\=\frac{400}{43}\\=9.30\ meters\ per\ second

<u>Unit rate for 300m Race:</u>

Distance = 300m

Time = 31 sec

Unit\ Rate= U_2=\frac{300}{31}\\=9.68\ meters\ per\ second

The difference between both unit rates is:

U_2-U_1 = 9.68-9.30\\=0.38 => 0.4\ meters\ per\ sec

Hence,

The difference between both unit rates rounded off to the nearest tenth is: 0.4 meters per second
