Speed of the boat in still water = 70/4 = 17.5 km/h Downstream speed of the boat = 72/3 = 24 km/h Speed of the stream = 24 – 17.5 = 6.5 km/h Upstream speed of the boat = 17.5 – 6.5 = 11 km/h Time taken to cover 66 km upstream and 48 km downstream = 66/11 + 48/24 = 6 + 2 = 8 hours
A man can row at 5 kmph in still water. If the velocity of current is 1 kmph and it takes him 5 hour to row to a place and come back, how far is the place?
A boat covers 36 km downstream in 2 hours, and it takes 3 hours to cover the same distance upstream. What is the speed of the current?
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...
The speed of a boat in still water is 25 km/hr. If the boat covers 240 km in upstream in 12 hours, then find the time taken by the boat to travel 177 km...
A boat covers 32 km upstream and 40km downstream in 8 hours while it covers 40km upstream and 32 km downstream in 8.5 hours. What is the velocity of cur...
Speed of boat in downstream is 45% more than speed of boat in still water. If speed of stream is 9 km/h, then find the time taken by the boat to cover 8...
A man takes 10 hours to row 21 km upstream from point A to point B and back to A by boat. If he takes the same time to row 7 km downstream as upstream. ...
What is the speed of boat in still water?
Statement I: It takes the boat thrice as much time to row up than as to row down the same distance in...
A boat running downstream covers a distance of 24 km in 3 hrs while it covers the same distance upstream in 6 hrs. Then speed of the boat in still water is
