Because 1.3 < dL = 1.5, there is positive autocorrelation.
The downstream speed of a boat is 6 km/hr more than its upstream speed and the ratio of the speed of the boat in still water to the speed of the stream ...
The speed of a boat in still water is 40 km/hr. If the boat covers 360 km in upstream in 12 hours, then find the time taken by the boat to travel 150 km...
A boat can cover 120 km in upstream in 6 hours and 180 km in downstream in 3 hours. Find the speed of the stream.
A motorboat in still water travels at a speed of 40 km/hr. It goes 45 km upstream in 2 hour 15 minutes. The time taken by it to cover the same distance ...
A boat covers a distance of 338 km upstream in 13 hours. After rain, the speed of the stream increases by 50%, and the speed of t...
A boat covers 45 km downstream in 2 h and the same distance upstream in 10 h. Find the speed (in km/h) of the boat in still water.
The ratio of downstream speed to upstream speed of a boat is 5:3. If the boat can cover 160 km in still water in 10 hours, then find the difference betw...
Speed of boat is 20 km/hr. Speed of the stream is 20% less than speed of boat. Then find time taken by boat to go 90 km downstream.
The ratio of speed of boat in upstream and in Stillwater is 1: 3 respectively. The boat takes a total of 10 hours to travel 300 kilometer in downstream ...
A ferry takes 108 minutes to row to place B from another place A along the stream. The distance between place A and place B is 32.4 km. If the speed of ...
