A boat covers a certain distance downstream in one hour, while it comes back in one and half hours. If speed of the stream be 3 kmph , what is the speed of the boat in still water?
Let s = the speed of the boat in still water.
s = 15 km/hr
If it ain't broke, fix it until it is.
A number by itself is useful, but it is far more useful to know how accurate or certain that number is.
