Question

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 3. how much time does it take for a bird flying at a speed of 45 kilometers per hour to travel a distance of 1,800 kilometers? equation: plug numbers into the equation final answer w/ units

Explanation:

Step1: Identify speed - distance - time formula

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

Step2: Solve for baseball's speed

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

Step3: For bird's time - identify formula

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

Step4: Solve for bird's time

Given $d = 1800$ kilometers and $v = 45$ km/h. Plug into the formula: $t=\frac{1800}{45}=40$ h.

Answer:

1. Equation: $v=\frac{d}{t}$

Plug numbers into the equation: $v=\frac{60}{0.5}$
Final Answer w/ units: 120 m/s

1. Equation: $t=\frac{d}{v}$

Plug numbers into the equation: $t=\frac{1800}{45}$
Final Answer w/ units: 40 h
