A boat sailing against a stream of of river takes 6 hours to travel 24 kms, while sailing with the stream it takes 4 hours to travels the same distance. What is the speed of the stream ? Correct Answer 1 km / hr

Let, Speed of stream = y & Speed of boat = x ATQ, x - y = 24/6 = 4— (i) x + y = 24/4 = 6 ——– (ii). From, (ii) – (i), x + y - x + y = 6 - 4 Or, 2y = 2 Or, y = 1 ∴ Speed of stream = 1 km/hr (ans)

If Rati travels at his usual speed for ‘x’ hours, he covers the same distance as he covered when he travels at a speed 30 km/hr less than usual, but for (x + 3) hours. Which of the following can be determined? (A) If he travels at 20 km/hr less speed than usual, he can cover a distance of 240 km in (x - 1) hours. What is the value of ‘x’? (B) If travels at his usual speed for (t + 2) hours, and at 50% of his usual speed for (t - 2) hours, his average speed for the journey is 68 km/hr. What is his usual speed? (C) His usual speed (in km/hr) is a multiple of 5 between 40 and 50 (both inclusive). If ‘x’ is a whole number, what is his usual speed?

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 the both quantities and chose the correct option. Quantity A: The ratio of speed of boat to speed of stream is 2 : 1, If the boat travels 162 km and come back to starting point in 36 hour. What is the difference between the time taken by the boat to go upstream and the time taken by the boat to go downstream? Quantity B: The speed of the stream is 6 km/hr and the distance travelled by the boat is 60 km. If the boat covered half distance upstream with usual speed and other half with double its speed, then it takes 7.5 hours less time than usual time to go upstream. Find the total time taken by the boat to go upstream and downstream?
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?
In river A, the distance travelled by a boat downstream in time T is 50% more than the distance travelled by the same boat upstream in the same time. In river B, the same boat travels a distance of 11 km upstream in 30 minutes. If the speed of the current in river B is 2 km/h, what is the speed of the stream in river A? (The speed of the boat in still water is same in both the rivers)
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: Superman and Batman in their boat are moving towards each other If Superman travel against the stream and Batman along the stream they are at a distance of 2300 km from each other. If the Speed of Stream is 20 km/h and Speed of Superman’s Boat is 100 km/h and Speed of Batman’s Boat is 130 km/h. Find the Time Taken to meet each other Quantity B: Tony Stark is flying in his suit 1 hour before Captain America with the speed of 200 km/h. If Captain America is chasing him in the boat which runs at a speed of 270 km/h against a stream which has speed of 20 km/h. Find the time in which he catches the Tony Stark.
The speed of Boat P is 3 km/h more than the speed of Boat Q. The time taken by Boat Q to travel a distance of 30 km downstream is 30 minutes more than the time taken by Boat P to travel the same distance downstream. If the speed of the current is 1/3 of the speed of Boat Q, then what is the speed of Boat P?
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 ?
