Answer: It takes the stone 7seconds in air and 5seconds in water
Explanation: complete question: How long did the stone fall in air and how long did it fall in the water?
total distance = sum of velocity * time for both legs of the journey;
let the time taken in air be t
hence time taken in water is 12-t
127 = 16*t + 3(12-t)
127 = 16t + 36 - 3t
127 - 36 = 16t - 3t
91 = 13t
t = 91/13 = 7 seconds
Hence time taken in air = 7 seconds
time taken in water is 12 - 7 = 5 seconds
