In air, sound waves travel as compressions and rarefactions, i.e., particles move back and forth along the direction of wave travel. Such waves are longitudinal.
The distance covered by a boat while moving in downstream in a fixed time is 3/4 more than in upstream. The speed of stream is what % of the still water...
The duration it takes for boat 'P' to cover 160 km downstream is equal to the duration it takes to cover 120 km upstream. If the ratio of the speed of b...
A man can row at 3 kmph in still water. If the velocity of current is 2 kmph and it takes him 6 hour to row to a place and come back, how far is the place?
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?
A boat can cover 40 km upstream and 60 km downstream in 13 hour. Also it can cover 50 km upstream and 72 km downstream in 16 hour. Find the speed of boa...
A boat can cover 60 km in still water and 75 km in downstream in 4 hours and 3 hours respectively. Find the time taken by the boat to cover 60 km upstre...
Speed of a boat in downstream is 50% more than that in upstream. Total time to travel 48 km upstream and 36 km downstream is 6 hours. What is the speed ...
A man takes 10 hours to row 21 km upstream from point A to point B and back to A by boat. If he takes the same time to row 7 km downstream as upstream. ...
A boat takes one-third time in moving a certain distance downstream than upstream. The ratio of the speed of the boat in still water and that of the cur...
Speed of boat is 20 km/hr. Speed of the stream is 15% less than speed of boat. Then find time taken by boat to go 74 km downstream?
