(I don't know what your question is, but if you're asking about the rate, I got it.)
Answer: 2.6666... meters per second
Explanation/Calculation:
Divide 40 by 15 to get the rate. You get 2 2/3 meters or 2.6666... meters per second.
Hope this helps! :)
1 -since everything includes 4a, we can factor that to get 4a(a-4b^3+2b^2c)
2 - since 5 and 3 add to 8 and multiply to 15, we can do (n+5)(n+3)
3 - since -5 and -4 add to -9 and multiply to 20, we can do (g-5)(g-4)
4 - since -10 and 3 add to -7 and multiply to 30, we can do (z-10)(z+3)
5 - we can factor out 4y to get 4y(y^2-9).
I got the numbers in 2, 3, and 4 with a guesstimating and checking approach
Factors of 54: 1, 2, 3, 6, 9, 18, 27, 54.
Answer:
Question 2:
45 pages 700 pages
-------------- = -------------
1 hour X hours

700/ 45= 15 and 5/9
15 and 5/9 hours
Question 3:
= 88.33 lbs
Answer:

Step-by-step explanation:
using the relationship between distance/ speed / time
distance = speed × time
speed =
=
= 62 mph
