Answer:
B. 120
Step-by-step explanation:
Each ribbon is 25 yards long. Each yard is 36 inches, so the length of the ribbon is ...
(25 yd)(36 in/yd) = 900 in
This can be divided into n pieces, where n satisfies ...
22n ≤ 900
n ≤ 900/22 = 40 20/22
That is, Erika can cut 40 22-inch pieces from each 25-yard piece, and will have 20 inches left over.
From the 3 25-yard pieces, Erica can cut 3×40 = 120 pieces of ribbon that are 22 inches long.
_____
She will have 3 pieces that are 20 inches left over.

Answer:
1.5 km/hour
Step-by-step explanation:
d is the David's speed in still water
c is the speed of the current
Going with the current, he travels d+c km per hour.
Going against the current, he travels d-c km per hour.
d+c = (20 km)/(2.5 hours) = 8 km/hour
d-c = (20 km)/(4 hours) = 5 km/hour
Add the equations to eliminate the c terms
d+c = 8
d-c = 5
----------
2d = 13
d = 6.5 km/hour
c = 8-d = 1.5 km/hour
