Question 951135: A boat can travel 27 mph in still water. If it travels 324 miles with the current in the same length of time it travels 162 miles against the current, what is the speed of the current? Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! time*speed=distance
t=time in hrs., c=speed of the current in m/h.
t(27+c)=324
t(27-c)=162
.
27t+ct=324
27t-ct=162
------------add
54t====486
.
t=9 hrs
.
9*(27+c)=324
243+9c=324
9c=81
c=9 m/h
