# A baseball is thrown a distance of 20 meters. What is its speed if it takes .5 seconds to cover the distance?

Dec 1, 2015

$40 \text{m/s}$

#### Explanation:

Average speed = distance travelled / time taken.

$= \frac{20}{0.5} = 40 \text{m/s}$

You shouldn't need any formula, just use common sense.

It goes 20m in half a sec. How far in 1 sec?
