Question

A man is in a boat 2 miles from the nearest point on the coast. He is to go to point *Q*, located 3 miles down the coast and 1 mile inland (see figure). He can row at a rate of 1 mile per hour and walk at 1 miles per hour. Toward what point on the coast should he row in order to reach point *Q* in the least time? (Round your answer to two decimal places.)

Same problem also attached. Thanks,

Step 1

Let *P* be the position of the boat in coast and let *O *be the point between coast and land.

The current situation can be represented as follows.

Step 2

By the Pythagoras theorem the distance *PO* computed as follows.

Step 3

By the Pythagoras theorem the distance ...
