Final answer:
The speed of the UFO that travels 250.0 km in 2.00 seconds is 125,000 m/s.
Step-by-step explanation:
To calculate the speed of the UFO, we need to convert the given distance from kilometers to meters and divide it by the given time in seconds.
Given: Distance = 250.0 km, Time = 2.00 seconds
First, let's convert the distance from kilometers to meters: 250.0 km = 250,000 meters.
Now, we can calculate the speed of the UFO using the formula:
Speed = Distance / Time
Speed = 250,000 meters / 2.00 seconds
Speed = 125,000 m/s
Therefore, the speed of the UFO is 125,000 m/s.
