relativity?Solution
Einstein proposed the theory of relativity in the early 20th century.
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 ...
Two boats A and B start towards each other from two places, 660 km apart. Speed of the boat A and B in still water are 30 km/h and 25 km/h respectively....
Ratio of speed of boat in still water and speed of stream is 5:2 respectively. Boat covers 42 km downstream in 3 hours. Find the upstream speed of boat.
The ratio of the speed of the boat in upstream to that of in downstream is 5:9, respectively. If the speed of the current is 7 km/h, then find the speed...
A swimmer swims from a point A against a current for 5 minutes and then swims current for next 5 minutes and comes to the point B. If AB is 100meters, t...
Speed of a boat in still water to speed of boat in upstream is 11: 9. If the boat can travel 260 km in downstream in 10 hours, then find the time taken ...
A man can row his boat with the stream at 42 km/h and against the stream in 7 km/hours. The man’s rate is
A boat takes 14 hours to cover 196 km upstream and 7 hours to cover the same distance downstream. Find the time taken by the boat to cover 168 km in sti...
A man can row at 30 km/hr in still water. If the velocity of current is 6 km/hr and it takes him 1 hour to row to a place and come back, how far is the ...
A boat takes 8 hours to cover 144 km in downstream. If the ratio of still water speed to downstream speed of boat is 2:3 respectively, then find the tim...
