the heart?Solution
The pulmonary veins transport oxygenated blood from the lungs to the left atrium of the heart.
Speed of a boat in still water is three times the speed of the boat in upstream. If the boat takes 35 minutes to cover 35 km in downstream, then find th...
The upstream speed of a motorboat is 14 km/hr. If the boat travels 256 km downstream in 8 hours, find the speed of the current.
- A boat travels 100 km upstream and 160 km downstream in 9 hours. If the speed of the boat in still water is 25 km/hr greater than the speed of the stream, ...
Speed of boat is 10 km/hr. Speed of the stream is 30% less than speed of boat. Then find time taken by boat to go 34 km downstream?
The downstream speed of a boat is 6 km/hr more than its upstream speed and the ratio of the speed of the boat in still water to the speed of the stream ...
The speed of current is 26 km/hr. If the speed of the boat in still water had been 12 km/hr more than the original speed then it would take 7.5 hours to...
When travelling downstream, a boat takes 4.25 hours to travel 187 km. If the speed of the stream is (5/11)th of downstream speed of the boat,...
A man can row his boat with the stream at 15 km/h and against the stream in 8 km/hours. The man’s rate is
Speed of stream 'L' is 3 km/h more than speed of stream 'M'. Sum of upstream speed of a boat in 'L' and its downstream speed in 'M' is 39 km/h. Time tak...
- Boat ‘L’ moves 1.5 times faster than boat ‘K’ in still water. If both boats start at the same time from locations 270 km apart and move towards eac...
