What is the distance covered by boat N upstream in 5 hours? Which of the following option is sufficient alone to find the answer? A) Boat M is travelling downstream with 20% more downstream speed of boat N. Speed of boat M in still water is 10% more than the speed of boat N in still water. B) Boat M and Boat N are travelling downstream with speed 33 km/hr and 40 km/hr respectively and speed of boat M is still water is 2 times the speed of stream. C) Speed of boat M in still water is 6 km/hr less then speed of boat N in still water and speed of stream is 10 km/hr. D) Speed of stream is ½ times the speed of boat N in still water and downstream speed of boat M is 44 km/hr. E) Speed of stream is 10 km/hr and ratio of upstream speed of boat M and boat N is 3 : 2 respectively.
Two cities Mathura and Agra, 48 kms apart, are located on the bank of River Yamuna. A motor boat goes from Mathura to Agra and returns back as soon as possible. Yamuna flows at a speed of 6 km/hr. The motorboat completes the trip from Mathura to Agra and back in not more than 6 hours. Assuming the motorboat does not halt at Agra, what should be the minimum speed of motorboat in still water?

A motorboat whose speed in still water is 15 km/hr, goes 30 km downstream and comes back in 4 hrs and 30 minutes. The speed of the stream (in km/hr) is
A Motorboat takes 24 hours for travelling downstream from a point A to point B and coming back to point C, which is 1/3rd of distance between A and B. if the speed of the stream is 15 km/hr and the speed of the Motorboat in still water is 30 km/hr, then find out the distance between B and C?
A motorboat, whose speed in 12 km / hr in still water goes 40 km upstream and comes back in a total of 7 hours 30 minutes. Find the speed of the stream (in km / hr).
Speed of boat in still water and speed of stream are 12.5 km / h and 2.5 km / h respectively. The boat goes ‘X’ km downstream and comes back 20 km upstream and takes total time of 5 hours, then what is the total time taken by the boat to go ‘(X - 15)’ km downstream and come back?
In the following question, two statements are numbered as A and B. On solving these statements, we get quantities A and B respectively. Solve both quantities and choose the correct option. Quantity A: Saurav can row a boat 40 km upstream in 8 hours. If speed of Saurav’s boat is 7 km/h. Find how much Saurav can row downstream in 9 hours. Quantity B: Vaibhav’s boat travelled 100 km in 10 hours in still water. If total time taken by Vaibhav to reach the distance is 8 hours for first half of time he goes against the stream and for remaining half along with the stream. Find the distance travelled, if speed of stream is 2 km/h.
Study the following questions carefully and answer accordingly. Quantity - I) If the time taken by a boat to cover the same distance in upstream is 2 hours more than downstream. The downstream speed of the boat and the speed of current is 16 kmph and 4 kmph then find the total distance travelled by the boat? Quantity - II) If the time taken by the boat in upstream and in downstream is 16 hours and 10 hours to cover the same distance. Then find the speed of boat in still water is how much percent of the speed of stream? Quantity – III) If the length of rectangle is twice of its breadth and 3 times more than the side of square and the difference between the side of square and length of rectangle is 15 cm then find the area of rectangle ?
A boat goes to 36 km downstream with the speed of the boat in still water 15 km/hr in still water and it goes to 28 km in upstream with the speed of 3/5 of the speed of the boat in still water. How much time was taken by the boat to cover the total distance, if the speed of the stream is 3 km/hr?
