I have the math problem answers- I need to show how to get them?
With the current, a boat can travel 48 m.p.h. in 3 hours.
Against the current, the boat requires 4 hours to travel the same distance
1.) Find the rate of the boat in calm water
2.) Find the rate of the current
Do I solve through substitution or elimination ?
Well, I have the answers; but I have to show how to get them. The boat speed in calm water is 14 m.p.h., and the current speed is 2 m.p.h. I have come up with 3 or 4 different answers

b = the rate of the boat in calm water
c = the rate of the current
(b+c) * 3 = 48
(b-c) * 4 = 48
b+c = 16
b-c = 12
2b = 28
b = 14
2c = 4
c = 2
