Urease, an enzyme found in soybeans among other sources, catalyzes the hydrolysis of urea into ammonia and carbon dioxide. It plays a critical role in nitrogen metabolism in some plants and bacteria.
The speed of a boat in calm water is 21 km/h. If the speed of the stream is 3 km/h, how long will it take for the boat to travel 63 km against the current?
The speed of a boat in still water is 6 km/hr more than that of the current. The time taken by the boat to cover 675 km downstream is 13.5 hours. Find t...
The speed of a boat in still water is 30 km/hr. If the boat covers 240 km in upstream in 12 hours, then find the time taken by the boat to travel 120 km...
A boat can travel 30 km downstream in 45 min. The ratio of the speed of the boat in still water to the speed of the stream is 5: 3. How much time will t...
The downstream speed of a boat is 8 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 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 half the time to move a certain distance downstream than upstream. the ratio of the boat's speed in still water and that of the current is.
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 boat covers 13 km upstream in 52 min. If the speed of the current is 6 km / h, then in how much time will it cover 40 km downstream?
Calculate the speed of a boat in still water if it travels 176 km downstream in 11 hours and returns 144 km upstream in 18 hours.
