Question
Select the option that is related to the third word in
the same way as the second word is related to the first word . Pressure: Pascal :: Energy: ?Solution
The SI unit of Pressure is Pascal. Similarly, the SI unit of Energy is Joule. Hence, option A.
If Boat goes 80 km upstream in 4 hours and 60 km downstream in 2 hours, then the speed of the boat in still water is
The speed of a boat while moving upstream is 20% less than its speed in still water. The boat covers a distance of 348 km downstream in 7 hours and 15 m...
Speed of current is equal to 35% of speed of boat in still water. If the boat takes 7 hours to cover 140 km in still water, then find the time taken by ...
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...
The difference between the time taken by a boat to travel 360 km upstream and 240 km downstream is 10 hours. The speed of the boat and the stream are οΏ½...
When travelling with the current, a man takes 9 hours to cover the distance that he would've covered in 15 hours while travelling against the current. I...
If the speed of the current is 4 km/hr and the ratio of the speed of the boat in downstream to the speed of the stream is 7:2, what is the distance trav...
The downstream speed of a boat is 48 km/hr, while its upstream speed is 32 km/hr. The boat takes 10 hours to travel a distance of (p + 40) km downstream...
A man can row one quarters of a kilometer against the stream in 30/4 minutes and return in 5/2 minutes. The speed of the man in still water is:
A boat travels 48 km downstream in 4 hours and 36 km upstream in 4 hours. Find the speed of the stream.
