Question 28
A crew can row 10 miles in 5/6th of an hour down-stream and 12 miles upstream
in 90 minutes. Find the current's rate and crew's rate in still water.
Solution
Let speed of crew= 'a' mph
Speed of current = 'b' mph
Downstream, the speeds will be added
Upstream, the speeds will be subtracted
a+b = $$\frac{\left(10\right)}{\frac{5}{6}}$$ = 12 miles/hr
a-b = $$\frac{\left(12\right)}{\frac{3}{2}}$$ = 8 miles/hr
Solving the above two equations, we get a = 10 mph and b as 2 mph.
Therefore, Option B is the correct answer.
