Frank stands still while throwing a dart toward a target with a speed of 25 m/s.
What is the speed of the dart observed by Frank compared to the speed observed by a stationary observer?
The speed is 25 m/s for both people.
The speed is greater than 25 m/s for Frank only.
The speed is greater than 25 m/s for the observer only.
The speed is less than 25 m/s for both people.

The speed is 25 m/s for both people.
Explanation: Frank is standing still, so the given 25 m/s is the speed relative to him (and to the ground). A stationary observer at rest relative to Frank measures the same speed. (If an observer were moving relative to Frank, their measured speed would differ by the observer's velocity.)
