It’s 10.5 I’m pretty sure
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 =<span> 5 seconds</span> checking; 16*7 + 3*5 = 127
