A motorboat travels 540 kilometers in 9 hours going upstream 432 kilometers in 4 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?

Let's say you are paddling at 5mph and the current is 3 mph. Going upstream, you are going 2 mph and downstream, 8 mph.

8(b - c) = 440

9(b + c) = 837

b - c = 55

b + c = 93

Adding the two together...

2b = 148

b = 74

74 - c = 55

c = 19

The boat's speed is 74 mph and the current's speed is 19 mph.

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
