Let the length of each side of the square field be ‘x’ meters. => 4a = 120 => x = 30 Area of square field = 30 × 30 = 900 m2 Area of a rectangular field = 900 × (165/100) = 1485 m2
Speed of a boat in still water to speed of boat in upstream is 8:5. If the boat can travel 440 km in downstream in 5 hours, then find the time taken by ...
A Boat travel 80 km distance in downstream and 48 km upstream and the total time taken is 20 hours. The same boat travels 30 km distance in downstream a...
A man can go on a motor boat with a speed of 15 km/hour in still water to a certain upstream point and come back to the starting point in a river which ...
A boat takes 24 hours to cover 'q' km in still water. While traveling downstream, it takes 16 hours to cover (q - 80) km. If the speed of the boat in st...
The ratio of the speed of a motorboat to that of a current of water is 36:5. The boat goes along with the current in 5 hours and 10 minutes it will come...
The speed of the boat upstream and downstream are in the ratio of 3:4. If the boat covers a distance of 147 km in still water in 7 hours, determine the...
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...
Speed of boat is 20 km/hr. Speed of the stream is 20% less than speed of boat. Then find time taken by boat to go 90 km downstream.
The speed of the current is 80% lower than the boat's speed in still water. The boat covers 120 km in still water in 8 hours. How long will it take for ...
