In an effort to reduce accidents, the highway authority decided to reduce the speed limit on a road from 65 mi/h to 50 mi/h. To travel 650 miles, how many more hours will it take a car averaging 50 mi/h than a car averaging 65 mi/h?

The answer is 3 hours

Step-by-step explanation:

The reason being, 65 mi/h can be divided by 650 to equal 10, so it would take 10 hours to get through those 650 miles with your car that drives 65 mi/h

Then we can do the same things with 50, that equals 13. So 13 - 10 = 3. It took the 50 mi/h car 3 more hours to get through 650 miles than the 65 mi/h car!

Hope this helped :)

7/2

(decimal: 3.5)

welcome ; )

step-by-step explanation:

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
