A man is camping on an island 1 km from the nearest point on the shoreline. He wants to go to the store which is 4 km down the shoreline. The man can paddle his canoe at 7 km /h and he can jog at 8 km /h. Find x, the horizontal distance along the shore, across from where his island is, that the man should aim to land his canoe in order to reach the store in the least time. Find your answer as a simplified rationalized fraction in the form Record your answer as AB, where a square root sign is to be shown as SR(_). 6V3 For example, 5 would be written as 6SR(3)5 or V2 8 would be written as SR(2)8.
