A boat can cover ‘y’ km distance downstream in (t+2.5) hours. The same boat can cover ‘0.25y’ km distance upstream in ‘t’ hours. The time ta...
A man can row upstream at 18 km/hr and downstream at 24 km/hr. Find the man’s rate in still water and the rate of the current.
...Speed of a boat in still water is three times the speed of the boat in upstream. If the boat takes 20 minutes to cover 20 km in downstream, then find th...
The ratio of the speed of the boat in upstream to that of in downstream is 7:10, respectively. If the speed of the current is 12 km/h, then find the spe...
