Answer:
That's slow.
Explanation:
25 meters in 15 seconds is the same as 1.67 meters per second. Converted to miles per hour, you get 3.735684 mph. Considering a human can run up to 15 mph, Mike's time is slow. However, it depends on what you're comparing his speed to. If we don't compare Mike's speed to the average human and compare it to someone else's speed instead, Mike could be fast.
