Answer: friend snorkeling just below the surface of the water

Explanation:

Sound travel faster in a denser medium than a less dense medium.

Since water is denser than air, sound will propagate faster in water than air. Therefore, a friend snorkeling just below the surface of the water would detect the sound of the motor first before a friend sitting on the shore of the lake at the same distance from the boat.
