Which one is not basis of classification of data.
The correct answer is C
A man rows upstream 18 km and downstream 30 km taking 6 hours each. Find the man’s speed in still water.
A man can row at 6 kmph in still water. If the velocity of current is 3 kmph and it takes him 8 hour to row to a place and come back, how far is the place?
A boat can travel 26 km downstream in 30 min. The ratio of the speed of the boat in still water to the speed of the stream is 8: 5. How much time will t...
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 speed of the boat and the speed of the stream is 15km/hr and 3km/hr individually. The boat travel for a period of 3 hours upstream and 4 hours downs...
A boat covers 32 km upstream and 40km downstream in 8 hours while it covers 40km upstream and 32 km downstream in `8 1/2` hours. What is the velocity of...
The ratio of the speed of boats ‘A’ and ‘B’ in still water is 8:9, respectively. The speed of the current is 25% of the speed of boat ‘A’ in...
The time taken by the boat to cover (d+130) km distance in downstream is 1.9 hours less than the time taken by the same boat to cover (d-45) km distance...
The ratio of the speed of boat ‘A’ in still water, the speed of boat ‘B’ in still water and the speed of the current is 11:5:2, respectively. If...
Speed of boat is 10 km/hr. Speed of the stream is 20% less than speed of boat. Then find time taken by boat to go 90 km downstream?
