Answer:
Time, t = 250 seconds
Explanation:
Speed with anchor with which it falls, v = 0.07 ft/s
A boat drops an anchor 17.5 feet to the bottom of a lake, d = 17.5 ft
Let t is the time taken by the anchor to reach the bottom of the lake. The speed of the anchor is given by :



t = 250 seconds
So, the time taken by the anchor to reach the bottom of the lake is 250 seconds. Hence, this is the required solution.
