Final answer:
The unicycle travels a distance of 300 meters at a speed of 20 m/s for 15 seconds.
Step-by-step explanation:
To find the distance traveled by the unicycle, we can use the formula:
Distance = Speed x Time
Given that the speed is 20 m/s and the time is 15 s, we can substitute these values into the formula:
Distance = 20 m/s x 15 s
= 300 m
Therefore, the unicycle travels a distance of 300 meters at a speed of 20 m/s for 15 seconds.
