Answer:
29 seconds
Explanation
anchor dropped in to water at the rate = 2.5 m/s
so for one second = 2.5 m
so for 45 sec= 2.5 x 45 = 112.5 m
but it was already 40 m under water, so it have fallen from= 112.5-40= 72.5 m
so as we know the rate of falling was =2.5 m/s
so for 72.5 meter, it took = 72.5 /2.5= 29 sec
it took for anchor to get down to the water surface after it started dropping.
