Answer:
It takes 58.8 seconds to swim the length of a olympic-sized pool.
Explanation:
Uniform Velocity Motion
It describes the situation when an object moves in such a way that it travels equal distances at equal times in the same direction. For example, if it travels x=50 m in t=10 seconds and later it travels x=200 m in t=40 seconds, its speed is constant and equal to v=5 m/s. The relation between the variables x,t, and v is
[tex]x=v.t[/tex]
We know a swimmer is traveling at a constant speed of 0.85 m/s. We are required to find how long would it take him to swim the length of an x=50-meter Olympic-sized pool.
From the above equation, we solve for t
[tex]\displaystyle t=\frac{x}{v}[/tex]
[tex]\displaystyle t=\frac{50\ m}{0.85\ m/s}[/tex]
[tex]\boxed{t=58.8\ s}[/tex]
It takes near 59 seconds to swim the length of a olympic-sized pool
