Final answer:
The speed of the jet plane that travels 550 meters in 4 seconds is 137.5 m/s.
Step-by-step explanation:
To find the speed of the jet plane, we use the formula:
Speed = Distance / Time
Given that the plane travels 550 meters in 4 seconds, we can substitute these values into the formula to solve for speed:
Speed = 550 meters / 4 seconds
Simplifying the equation, we get:
Speed = 137.5 meters per second (m/s)
Therefore, the correct answer is 137.5 m/s.
