The speed of a boat in still water is 16 km/hour 16 km/hour 16 km/hour . It goes 60 km 60 km 60 km upstream and return downstream to starting point in 8 hours 8 hours 8 hours . Find the speed of the stream.
Answer:
4 km/hour
- Let the speed of stream be x km/hourx km/hourx km/hour.
- Thus,
Downstream speed = (16+x) km/hour(16+x) km/hour(16+x) km/hour
Upstream speed = (16−x) km/hour(16−x) km/hour(16−x) km/hour - Its is given that, total time taken = 8 hours8 hours8 hours
So, [Math Processing Error] - Hence, the speed of the stream is 4 km/hour.
