Explanation:

An object is released at one bank into a river flowing with speed 5km/h towards east. Air is blowing with speed 5km/h towards north. If width of river is 200m, then minimum time taken by floating object to reach the other bank is?

Air is blowing with speed 5km/h towards north

Width of River = 200 m = 200/1000 = 0.2 km

Time taken to reach other Bank =  0.2/5  =  0.04 hr  = 2.4 Minutes
