Swati can row her boat at a speed of 5 km/h in still water. If it takes her 1 hour more to row the boat
5.25 km upstream than to return downstream, find the speed of the stream.

Step-by-step explanation:
lest take speed of the stream as 'x'.
not time taken to row up stream =distance/speed
now, distance is 5.25 Km
speed is Speed of rowing - speed of the stream
=(5 - x)Km/hr
now, down steam.
distance = 5.25 Km
speed during down stream = speed of rowing + speed of the stream.
=(5+'x') km/ hr
difference of the time taken to row upstream and down stream is 1 hr.
(5.25/(5 - x)) - (5.25/(5 + 'x' )) = 1
by simplifying we get
3.3 Km/hr
hope this helps
thank you
