A car travels 4.5 miles in 5 minutes.
Work out the average speed in miles per hour.

about 54 miles per hour

Step-by-step explanation:

the car travels 4.5 miles in 5 mins so therefore you find out how many 5 mins are in 1 hours by doing 60 divided by 5 which is 12 than you do 12 times 4.5 to get 54

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
