You can do this: since 1/4 is .25 then just multiply 8 x .25
Let s be the speed of the boat in still water.
Let c be the speed of the current.
s - c = 48/6 = 8
s + c = 48/4 = 12
Adding the two equations, we get:
2s = 20
s = 10
The answer is 10 miles per hour.
Answer:
C. -3
Step-by-step explanation:
Find the slope through rise/run.
Notice that every perfect point is away from each other and you need to go up 3 times and left once.
so the slope is rise/run = 3/-1 or -3/1 or -3
The answer is 16/10 = 40/25
You divided 16 by 40 to see what you need to multiply 16 to get 40. When I did that I got 2.5. So I did that to the 10 and got 25 minutes. Hope this makes sense
