What is the speed of the boat in still water?

Mia took 3 hours to make a trip downstream with a 6mph current. The return trip against the current took 5 hours. ind the speed of the boat in still water. Explain

1. r+c downstream r-c upstream c=current r=rate of the river/boat in still wtaer r+c=3 r-c=5
2. Let the speed of the boat in still water be x Speed of the current is 6 Speed downstream is (x + 6) Speed upstream is (x - 6) Using d = st, Downstream: d = 3(x + 6) Upstream: d = 5(x - 6) Since it`s the same distance upstream as downstream, then: 3(x + 6) = 5(x - 6), so 3x + 18 = 5x - 30, so 48 = 2x, so x = 24. So the speed of the boat in still water is 24 mph
