I. 3x² - 22 x + 40 = 0 3x² - 12x - 10x + 40 = 0 3x (x – 4) – 10 (x – 4) (3x – 10 ) (x – 4) x = 10/3, 4 II. 4y² + 22y + 24 = 0 4y² + 16 y + 6 y + 24 = 0 4y (y + 4) + 6( y + 4) (4y + 6) (y + 4) x = - 4 , - 3/2 Hence, x > y.
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 72 km downstream?
If the sum of upstream and downstream speed is 48 km/hr and the speed of the current is 4 km/hr. Then find time taken to cover 84 km in downward?
When travelling downstream, a boat takes 6 hours to travel 240 km. If the speed of the stream is (3/8)th of downstream speed of the boat, the...
The speed of a boat in still water is 11 times the speed of the stream. If the difference between the upstream and downstream speed of the boats is 20 k...
The speed of a boat in still water is three times the speed of the boat upstream. If the boat takes 30 minutes to cover 27 km downstream, then find the ...
A man can row 25/2 km an hour in still water and he finds that it takes him thrice as long to row up as to row down the river. The rate of stream is:
The speed of the boat in still water is 40% less than the speed of the boat in downstream. The time taken by the boat to cover 468 km distance in upstre...
A man can row 5 km/hr in still water. If the speed of the current is 2 km/hr, it takes 4 hours more in upstream than in the downstream for the same dist...
A swimmer can swim at a speed of 3.5 kilometers per hour in still water. If the time taken to cover a certain distance upstream is 2.5 times the time ta...
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...
