# A motorboat has to cross a river 1km wide and flow of water is 5km/hr. Assuming the boat moves with uniform velocity of 15km/hr throughout, find the direction in which it should move to reach the other bank in the minimum time. Where and when it will reach the other bank? If the boat has to touch exactly the opposite bank, in which direction should it be set and how much time is required for it to reach opposite bank
