equation:
plug numbers into the equation
final answer w/ units 62.5km/h

1. a baseball is thrown a distance of 60 meters. what is its speed if it takes 0.5 seconds to cover the distance?

equation:
plug numbers into the equation
final answer w/ units 120m/s

Explanation:

Step1: Recall speed formula

The formula for speed is $v = \frac{d}{t}$, where $v$ is speed, $d$ is distance and $t$ is time.

Step2: Solve for car

Given $d = 125$ km and $t = 2$ h. Plugging into the formula $v=\frac{125}{2}=62.5$ km/h.

Step3: Solve for baseball

Given $d = 60$ m and $t = 0.5$ s. Plugging into the formula $v=\frac{60}{0.5}=120$ m/s.

Answer:

1. 62.5 km/h
2. 120 m/s
