Claudia Goldin was awarded the 2023 Nobel Prize in Economic Sciences for her comprehensive research and analysis of women's labor market outcomes. Her work has significantly enhanced the understanding of the economic forces affecting women's employment and earnings across history.
If the sum of upstream and downstream speed is 30 km/hr and the speed of the current is 5 km/hr. Then find time taken to cover 40 km in downward?
If a river is flowing at a rate of 6 km/hr and a boat's speed in still water is 150% higher than the river's speed, and the boat travels 'd' kilometers ...
The time taken by a boat to travel (5p + 60) km upstream is equal to the time taken to travel (8p - 40) km downstream. Given that...
When travelling downstream, a boat takes 5 hours to travel 240 km. If the speed of the stream is (5/8)th of downstream speed of the boat, the...
A boat takes 7 hours to cover 294 km upstream and 9 hours to cover 486 km downstream. Find the time taken by the boat to cover 720 km upstream and 616 k...
A boat can cover 130 km in downstream in 10 hours and 120 km in upstream in 12 hours. Find the distance travelled by the boat in still water in 4 hours.
The ratio between the time taken by a boat to cover a certain distance in upstream and the same distance in downstream is 5:1 respectively. The same boa...
A boat takes 5 hours to cover 190 km upstream and 8 hours to cover 416 km downstream. Find the time taken by the boat to cover 528 km upstream and 540 k...
A man goes downstream with a boat to some destination and returns upstream to his original place in 6 hours. If the speed of the boat in still water and...
The speed of the stream is 20 km/h. Boat ‘A’ covers 120 km distance against the stream in 6 hours and boat ‘B’ covers 120 km distance against th...
