At his usual rowing rate , Rahul can travel 12 miles downstream in a certain river in 6 hours less than it take him o travel the same distance upstream. But if he could double his usual rowing rate for his 24 mile round trip , the downstream 12 miles would then take only one hour less han he upstream 12 miles. what is he speed of the current in miles per hour ?
A boat covers 24 km upstream and 36 km downstream in 6 hours while it covers 36 km upstream and 24 km downstream in `6 1/2` hours. The velocity of the current is :
A man rows to a place 48 km distant and back in 14 hours. He finds that he can row 4 km with the stream in the same time as 3 km against the stream . The rate of one stream is :
A boat takes 90 minutes less to travel 36 miles downstream than to travel the same distance upstream . If the speed of the boat in still water is 10 mph, the speed of the stream is :
The speed of a boat in still water is 10 km/hr . If i can ravel 26 km downstream and 14 km upstream in the same time , the speed of he stream is :
