Answer 2

Finding the shortest route. A man in a rowboat 4 kilometers from the nearest point on a straight shore wishes to reach his house 8 kilometers down the shore. If he can row at a rate of 2kph and walk at rate of 4kph, how should he proceed in order to arrive at his house in the shortest possible time?

Answer 5

Let's consider the two most probable routes.
1) The man rows directly to the shore at 2kmph, then walks home at 4 kmph. That takes:
2 hours rowing + 2 hours walking = 4 hours
2) The man rows directly towards the house at 2 kmph, so make a right triangle...it would be a lot more.
So, I'd say the first option is much faster, because you are getting the slow part out of the way as quickly as possible.

Answer 6
