It takes 5 days for a steamboat to travel from A to B along a river. It takes 7 days to return from B to A. How many days will it take for a raft to drift from A to B (assuming all speeds are constant)?
A question is given, followed by three statements labelled I, II and III. Identify which of the statements is/are sufficient to answer the question.
Question:
How much time (in hours) will a boat take to go 25 km downstream?
Statements:
I. The time taken by the boat to go a certain distance downstream is of the time taken by it to go the same distance in still water.
II. The boat takes 6 hours to go 49 km downstream and 14 km upstream.
III. The ratio of the speed of the boat in still water and the speed of the current is 7 : 3.
Rivers A and B with constant water speeds a and b merge at point P to form river C with a constant water speed c.
A boat having speed s in still water would reach point R from Q only ifs is more than.
A person swims at a speed of 6 km/h downstream and 2 km/h upstream. His speed in still water is.
A boatman goes 2 km against the current of the stream in 1 hour and goes 1 km along with the current in 10 minutes. How long will it take to go 6 km in stationary water?
A man rows at 5km/h in still water. If the river is running at 1km/h, it takes him 75 minutes to row to a place and back. How for is the place?
Vishal covers 285 km in a boat in 45 hours against the stream and he takes 18 hours with the stream then find the speed of the stream?
A diver rowing at the speed of 3 km/h in still water takes double the time going 50 km upstream compared to going 50 km downstream. The speed of the diver downstream is:
