Complete question:
If the swimmer could cross a 14 km channel maintaining the same average velocity as for the first 50 m in the pool, how long would it take?
For the first 50m in the pool, the average velocity was 2.08 m/s
Answer:
It would take for the swimmer approximately 1.87 hours.
Explanation:
If the swimmer maintains the average velocity on the channel, we should find and approximate value of the time it takes to cross the channel with the Galileo’s kinematic equation:
With x the displacement, v the average velocity and t the time, solving for t:
