Question

A motorboat travels 384km in 6 hours going upstream and 408 km in 4 hours going downstream. What is the rate of the boat in still water and what is the rate of the current? PLEASE HELP

Answer 1

Please Help.

Answer 2

Let x be the rate of the boat in still water and y be the rate of the current.
The rates are distance over time
For upstream subtract the current.
x - y = 384/6
For downstream add the current
x + y = 408/4

Answer 3

I understand the concept but I'm still getting the wrong answers, could you show me what you got and how you go it please?

Answer 4

x - y = 64
x + y = 102

Add the equations together to eliminate y
2x = 166
x = 83 km/h

Then substitute to get y.
