speed with no wind = s
speed with wind = s + 5
speed against wind = s - 5
time = t
speed = distance/time
distance = speed * time
With wind, time = t, speed = s + 5, distance = 50
50 = (s + 5)t
Against wind, time = t, speed = s - 5, distance = 30
30 = (s - 5)t
t = 30/(s - 5)
50 = (s + 5) * 30/(s - 5)
50(s - 5) = (s + 5) * 30
50s - 250 = 30s + 150
20s = 400
s = 20
Answer: 20 mph

Answer:
0.16 bags
Step-by-step explanation:
Given that:
the floor of the rabbit's cage is 4 feet long and one bag of shaving covers 5² ft.
the floor of the rabbit's cage which is 4ft = 25 ft for one bag of wood shaving
to determine the amount of wood shaving Harper needs to buy to cover 4 feet of her rabbit's cage ; we have:
x bags = 4 feet
1 bag = 25 feet

x = 0.16 bags of wood shaving is needed to cover the floor of of the rabbit's cage that measures 4 feet long.
Step-by-step explanation:
Let's assume Debbie paid $1700 in interest, while Jan paid $9000.
Debbie Saves = $1700* 0.28
Jan Saves = $9000 * 0.28
Debbie Saves $476 in taxes
Jan Saves $2520 in taxes
