ATQ,
Let the speed of boat in still water and speed of stream be 7v and 2v km/h respectively.
So, (7v + 2v) × (96/60) = 50.4
Or, 9v × 1.6 = 50.4
Or, 9v = 31.5
Or, v = 3.5
Therefore, upstream speed = 7v - 2v = 5v = 5 × 3.5 = 17.5 km/h
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
