6. Michael Johnson holds the Olympic record for the men's 400m race at 43 seconds. His

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,

Unit rate for 400m race:

Distance = 400m

Time = 43 sec

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

Unit rate for 300m Race:

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

Find the distance between -2 1/2 and -5 3/4 on a number line

Elena-2011 [213]

Answer:

13/4

Step-by-step explanation:

Convert these numbers to a mixed fraction.

-5 3/4 => -23/4

-2 1/2 => -5/2

Make them have a common denominator

-5/2 => -10/4

-23/4 can stay the same.

To find the distance between the two numbers, subtract the lesser value from the greater value.

-23/4 is less than -10/4.

(-10 - (-23)) /4

= 13/4

Therefore the distance between -2 1/2 and -5 3/4 on a number line is 13/4.
