A man can row 6 km / hr in still water. It the speed of the current is 2 km / hr , it takes 3 hrs more in upstream than in the downstream for the same distance . The distance is Correct Answer 24 km

Speed of man in still water, x = 6 km/h Speed of current, y = 2 km/h Let distance = M According to question, Upstream time = Downstream time + 3 Or, M/4 = M/8 + 3 Or, 2M - M = 24 Or, M = 24 So, the distance is 24 km.

In the following question, two statements are numbered as A and B. On solving these statements we get quantities A and B respectively. Solve for both quantities and chose the correct option. Quantity A: A man takes 11/9 times downstream time to row upstream keeping the distance same in both cases. What is the speed of boat (m/s) in still water if it takes 6 hours to travel 80 km in downstream? Quantity B: A boat running in upstream covers 20 km distance in 3 hours while covering the same distance in downstream it takes 2 hours. What is the speed of the boat in still water (m/s)?
Given below are two quantities named A & B. Based on the given information, you have to determine the relation between the two quantities. You should use the given data and your knowledge of Mathematics to choose between the possible answers Quantity A: A man can row at 28/3 km/hr speed in still water and he finds that it takes him thrice as much time to row upstream as to row downstream. Find the speed of current. Quantity B: The speed of a boat in still water is 10 km/hr. If it can travel 26 km downstream and 14 km upstream in the same time, what is the speed of the stream?
Questions below followed by two quantities. Find the relation between them. The table shows the distance travelled by five different boats upstream, the speed of the boat in still water and the time taken by them to cover the upstream distance. Boats Upstream distance Speed of boat Time taken  A  240 km  15 km/hr  20 hr  B  150 km  10 km/hr  25 hr  C  350 km  20 km/hr  50 hr  D  96 km  8 km/hr  16 hr  E  126 km  26 km/hr  9 hr   Quantity I: Boat B travel 238 km distance downstream in certain time. How much downstream distance boat D will cover at the same time? Quantity II: Boat E travel 722 km distance downstream in certain time. How much downstream distance boat A will cover at the same time?
Compare the values of the two quantities in the question and answer. Quantity 1: A boat takes 3 hrs. 20 min. to travel 40 km upstream and 2 hrs.40 min. to travel the same distance in still water. How much time will it take to cover the same distance downstream? Quantity 2: The downstream speed of a boat is 22 km/hr and upstream speed is 17 km/hr. How much time will it take to travel 45 km in still water?
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 ?
