Help please!! thank you

B

Step-by-step explanation:

It is a 379 page book so the answer is 379. That leaves B and D. It states she has already read 54 so that eliminates D leaving B. Now let's say we want more proof. It states 28 pages an hour. That means 28h. D doesn't have this either.

what is the original number? you forgot to add it.

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
