Answer:
1/8 is half of 1/4 so, you need to measure half cup
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.
Its B on edgeuity just took the quiz
(s is greater or equal than 4)
