 Which language is used to access and manipulate data
in databases?Solution
Explanation: SQL is specifically designed to interact with databases.
A boat can travel 30 km downstream in 2 hours and 18 km upstream in 3 hours. How much time (in hours) will it take to travel 21 km in still water?
A man can row one quarters of a kilometer against the stream in 30/4 minutes and return in 5/2 minutes. The speed of the man in still water is:
A swimmer swims from point P against the current for 6 minutes and then swims back along the current for the next 6 minutes and reaches point Q. If the ...
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?
The speed of a boat in still water is 200% higher than the speed of stream. If the boat takes 4 hours to cover 96 km downstream, find the time it will t...
The speed of boat downstream and upstream is 28 km/hr and 18 km/hr respectively. Time taken to travel a distance of (m + 35) km downstream and (n + 22) ...
Speed of a boat in still water to speed of boat in upstream is 11:7. If the boat can travel 300 km in downstream in 5 hours, then find the time taken by...
A man can row one quarters of a kilometer against the stream in 30/4 minutes and return in 5/2 minutes. The speed of the man in still water is:
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...
A boat can cover 145 km in downstream in 5 hours and 144 km in upstream in 8 hours. Find the speed of boat in still water.
