Answer:
The time needed for Spongebob to swim that distance = 192.77 seconds
Explanation:
From the laws of motion, we have that the time it takes a person (in this case, Spongebob) to move from one location to another, or through a distance, equals the distance covered divided by the speed.
i.e time = distance / speed
Velocity of Spongebob's swim = 8.3 m/s
Distance swam = 1600 metres
Time taken = 1600/8.3 = 192.77 seconds
