What is the smallest unit of life.
The cell is the basic structural, functional, and biological unit of all living organisms.
A man can row upstream at 18 km/hr and downstream at 24 km/hr. Find the man’s rate in still water and the rate of the current.
...Find the total distance covered by boat in each upstream and downstream in 5 hours if the speed of boat in still water and speed of current is 20 km/h a...
A man can row at 6 kmph in still water. If the velocity of current is 4 kmph and it takes him 6 hour to row to a place and come back, how far is the place?
A submarine can travel a certain distance downstream in 4 hours and the same distance upstream in 8 hours. If the submarine's speed in still water is 12...
Find the total distance covered by boat in still water in 8 hours if the speed of boat in upstream and in downstream is 10 km/h and 15 km/h respectively?
A boat's speed in calm water exceeds the speed of the current by 12 km/hr. Given that the current's speed is 1.25x km/hr and the boat takes 5 hours to t...
The speed of a boat in still water is 6 km/hr more than that of the current. The time taken by the boat to cover 875 km downstream is 17.5 hours. Find t...
