(solution) The Speed of a current is 6mph. If a boat travels 60 miles

The Speed of a current is 6mph. If a boat travels 60 miles downstream in the same time that it takes to travel 30 miles upstream, what is the speed of the boat in still water?

The Speed of a current is 6mph
y be the speed of the boat in still water
boat travels 60 miles downstream
60
That is
y6
to travel 30 miles upstream
30
That is
y6
Same time
So that:
60
30 y 6 y 6
60…
