Answer:

A) 83 km/ hour

B) 2/7 penalties / game

C) $16 / CD

D) 9 donuts / box

Step-by-step explanation:

A)

For this question they are asking for the distance traveled in 1 hour.

Since 747km was travelled in 9 hours, we divide 747 by 9 to find the distance travelled in 1 hour

747 ÷ 9 = 83

The unit rate is 83 km/ hour

B)

You have to find the number of penalties per game

Like before divide 10 by 35:

10 ÷ 35 = 10/35 = 2/7

2/7 penalties / game

C)

Find the cost of 1 CD :

64 / 4 = 16

$16 / CD

D)

Find the amount of donuts per box:

72/8 = 9

9 donuts per box
