Xerox demonstrated the potential of a graphical user interface and mouse years before the personal computer market took off. Both Microsoft and Apple paid millions of dollars in stocks to license the technology for their own operating systems.
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 8:6:2, respectively. If ...
The speed of a boat in still water is 6 km/hr and speed of current is 4 km/hr. If time taken to cover a certain distance upstream is 10 hours, then how ...
A boat can travel 10 km more in downstream than that in upstream, in 5 hours while the difference between the time taken by the same boat to travel 250 ...
A boatman takes 9 hours to cover 64 km downstream and 60 km upstream. If the ratio of his speed downstream to his speed upstream is 4:3, what is the spe...
Speed of a boat in still water is three times the speed of the boat in upstream. If the boat takes 40 minutes to cover 15 km in downstream, then find th...
The downstream speed of a boat is 22 km/hr, and its upstream speed is 14 km/hr. Determine the time required for the boat to trave...
A boat's speed in still water allows it to cover 120 km in 8 hours. The current's speed is 20% of the boat's speed. How long will it take the boat to tr...
A boat takes 2 hours to travel 24 km downstream and 4 hours to travel 16 km upstream. What is the speed of the boat in still water?
A man can row 12 km/hr in still water. If the speed of the current is 3 km/hr, it takes 4 hours more in upstream than in the downstream for the same dis...
