Question
Which type of computers are used for solving complex
application such as Global Weather Forecasting.Solution
The correct answer is A
A boat can cover 40 km upstream and 60 km downstream in 13 hour. Also it can cover 50 km upstream and 72 km downstream in 16 hour. Find the speed of boa...
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...
A man rows 40 km upstream and 60 km downstream in 8 hours. If the ratio of his upstream speed to downstream speed is 2:3, then find the time required to...
A boat goes 5 km an hour in still water, but takes twice as much time in going the same distance against the current. The speed of the current (in km/ho...
Ratio of speed of boat in downstream and speed of stream is 5:3, if speed of current is 9 km/hr, then find distance travelled (in km) upstream in 8 hours.
- Ratio of speed of a boat in still water to speed of stream is 14:2 respectively.Ratio of the time taken by the boat to cover a distance of (x + 42) km upst...
The speed of a boat is that of the current of water is 35:6. The boat goes along with the current in 5 hours 10 minutes. Approximately at what time it w...
Ratio of downstream and upstream speed of a boat is 5:2. If the speed of stream is 3 km/h, find the distance travelled by boat in downstream in 2 hours.
A man rows upstream 36 km and downstream 51 km taking 3 hours each. Find the man’s speed in still water.
A boy can swim a certain distance downstream in 5 hours and return in 7 hours. If the rate of stream is 4 kmph then what is the speed of boy in still wa...
