T ≥ U > Y = V ? Z ≥ W > A T ≥ U > Y = V > Z ≥ W > A Y ≥ W true and T > Z false Hence, the ‘>’ symbol satisfies both the conditions.
If the sum of upstream and downstream speed is 20 km/hr and the speed of the current is 5 km/hr. Then find time taken to cover 45 km in downward?
A boat covers a certain distance upstream in 6 hrs and comes back to starting point with current in 3 hrs, If boat's upstream speed is 15 km/hr, then, f...
The speed of a boat in still water increases by 4 km/hour after each hour. The speed of stream is 3 km/hour. If the boat travelled 60 km in 3 hours in d...
A steamer covers 80 km in 5 hr. in still water. If the speed of the steamer in still water is 50% more than that of the stream, then time is required fo...
A boat takes 12 hours longer to cover 378 km upstream than it does to cover the same distance downstream. The speed of the stream...
A boat can cover 130 km in downstream in 10 hours and 120 km in upstream in 8 hours. Find the speed of boat in still water
A boat travels 30 km upstream and 45 km downstream in 6 hours. If the speed of the stream is 4 km/h and the boat’s speed in still water is 8 km/h, wha...
The time taken by a boat to cover 72 km downstream is 3 hours less than the boat to cover a certain distance in upstream. The dow...
A boat can travel 36 km downstream in 40 min. The ratio of the speed of the boat in still water to the speed of the stream is 5: 4. How much time will t...
The ratio of the speed of the boat in upstream to that of in downstream is 5:9, respectively. If the speed of the current is 7 km/h, then find the speed...
