A swimmer achieves an average velocity of 1.97 m/s while swimming a distance of 65.0 m. How long does this take in seconds?

A. 21.4 s
B. 16.6 s
C. 98.5 s
D. 33.0 s

Answer :

The time it takes for the swimmer to swim 65.0 meters at an average velocity of 1.97 m/s is D) 33.0 s

To find out how long it takes the swimmer to swim 65.0 meters with an average velocity of 1.97 m/s, we can use the formula for velocity:

[tex]v = \frac{d}{t}[/tex]

where:

  • [tex]v[/tex] is the velocity (1.97 m/s)
  • [tex]d[/tex] is the distance (65.0 m)
  • [tex]t[/tex] is the time in seconds

We need to solve for time [tex]t[/tex], so we rearrange the formula to:

[tex]t = \frac{d}{v}[/tex]

Substitute the given values:

[tex]t = \frac{65.0 \text{ m}}{1.97 \text{ m/s}}[/tex]

When we calculate this, we get:

[tex]t \approx 33.0 \text{ seconds}[/tex]
