Answer:
2 seconds.
Step-by-step explanation:
To answer we will use a rule of three where we know that the cyclist travels 380 meters in 20 seconds and we want to know how many seconds will it take to travel 38 meters. So:
380 meters ----------- 20 seconds
38 meters ---------- X
Where X is the number of seconds that the cyclist required to travel 38 meters.
So, solving for X, we get:

Therefore, the answer is 2 seconds.
