Answer:
Let b = rate of the boat.
Let r = rate of the river.
The rate going downstream is b + r.
The rate going upstream is b - r.
rate x time = distance
4(b + r) = 144 ---> b + r = 36 [divide both sides by 4]
9(b - r) = 144 ---> b - r = 16 [divide both sides by 9]
Add town: 2b = 52
Divide by : b = 26 mi/hr
r = 10 mi/hr
Step-by-step explanation:
Answer:
r < 12.5
Step-by-step explanation:
Given
150 - 5r > 87.5 ( subtract 150 from both sides )
- 5r > - 62.5
Divide both sides by - 5, reversing the symbol as a result of dividing by a negative quantity.
r < 12.5
