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

Question

m/s.

Answer 1

To calculate the average speed, you can use the formula:

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

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

Now plug in the values:

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

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