2mph - 30 minutes per mile : 2.5 mph - 24 minutes per mile : 3 mph - 20 minutes per mile: 4 mph - 15 minutes per mile : 4.5 mph - 13 minutes per mile : If you use metric units instead of Imperial, you may want to use the Pace Calculator to convert minutes per kilometer into minutes per mile and kilometers per hour into miles per hour.
In15 mins the boat travels 1 km downstream. Then, in (15 × 4) = 60 mins boat travels = 1 × 4 = 4 km/hr. Speed in Downstream = 4 km/hr. Speed in still water = (4 + 2)/2 = 3 km/hr. So, the time is taken by the boat to go 5 km in stationary water = Distance/Speed = 5/3 hrs = 1 hr 40 minutes. ∴ The time taken by the boat to go 5 km in
