- A ferry can travel twice as fast when empty as when it is full. It travels 20 miles with full load, spends 1 hours for unloading & returns to its original port empty. It took 11 hours to complete the journey. What is the speed when the ferry is empty?
- Speed of the boat in standing water is 6 km/h and the speed of the stream is 2 km/h. What will be the total time if a man goes by the boat upstream 32 km and comes back to the starting point?
- A man can row upstream at 10 km/h and downstream at 16 km/h. His rate in still water is---
- The speed of a boat in still water is 10 km/hr. If it can travel 26 km downstream and 14 km upstream in the same time, the speed of the stream is:
- In a stream running at 2 km/hr, a motor boat goes 10 km upstream and back again to the starting point in 55 minutes. Find the speed of the motor boat in the still water.
