Step-by-step explanation:
Distance = rate × time
If B is the rate of the boat, and C is the rate of the current, then we can write two equations:
18 = (B + C) × 3
18 = (B − C) × 9
Simplifying the equations:
6 = B + C
2 = B − C
Add the equations together to eliminate C:
8 = 2B
B = 4
Plug into either equation to find C:
C = 2
The boat's rate is 4 mph, and the current's rate is 2 mph.

Answer: 350
Step-by-step explanation: If you multiply the amount of <em>workers</em> by two, then you divide the amount of <em>time </em>by two, and vice versa. So, in other words, whatever number you multiply the workers by, divide the time by that same number. I hope this helps!
