A swimmer swims 20 m in 40 s. The swimmer's average speed is_____ m/s.

Answer 1

To calculate the average speed of the swimmer, you can use the formula for average speed:

\[ \text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}} \]

In this case, the total distance the swimmer swims is 20 meters, and the total time taken is 40 seconds.

Substituting the values into the formula:

\[ \text{Average Speed} = \frac{20 \text{ m}}{40 \text{ s}} = 0.5 \text{ m/s} \]

So, the swimmer's average speed is 0.5 m/s.
