Let's solve each problem step by step using the formula:
$$
\text{Speed} = \frac{\text{Distance}}{\text{Time}} \quad \text{or} \quad v = \frac{d}{t}
$$
We'll use this formula for all parts. Make sure to include units in your final answers.

1. Calculate the speed for a car that went a distance of 125 kilometers in 2 hours.
Equation:
$$
v = \frac{d}{t}
$$
Plug numbers into the equation:
$$
v = \frac{125 \, \text{km}}{2 \, \text{h}}
$$
Final answer:
$$
v = 62.5 \, \text{km/h}

2. A baseball is thrown a distance of 20 meters. What is its speed if it takes 0.5 seconds to cover the distance?
Equation:
$$
v = \frac{d}{t}
$$
Plug numbers into the equation:
$$
v = \frac{20 \, \text{m}}{0.5 \, \text{s}}
$$
Final answer:
$$
v = 40 \, \text{m/s}

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?
Now we rearrange the formula:
$$
t = \frac{d}{v}
$$
Equation:
$$
t = \frac{d}{v}
$$
Plug numbers into the equation:
$$
t = \frac{1800 \, \text{km}}{45 \, \text{km/h}}
$$
Final answer:
$$
t = 40 \, \text{hours}

4. A comet is traveling through the Solar System at a speed of 50,000 kilometers per hour for a 1-hour time. What is the total distance traveled by the comet during this time?
Now use:
$$
d = v \times t
$$
Equation:
$$
d = v \times t
$$
Plug numbers into the equation:
$$
d = 50,000 \, \text{km/h} \times 1 \, \text{h}
$$
Final answer:
$$
d = 50,000 \, \text{km}
$$
