A student can row a boat 6km/h in still waters, she is on one bank of a 6 km wide river that has current of 3km/h. Assuming she is allowed to land anywhere on the shore: (i) What is the smallest amount of time she needs to get to the opposite bank? (ii) What is the student’s speed as viewed by the observer on the bank?
