Final answer:
To determine the distance the girl traveled, we multiply her cycling speed of 5m/s by the time of 3 minutes (converted to 180 seconds), yielding a distance of 900 meters.
Step-by-step explanation:
The question asks about the distance a girl travels while cycling at a constant speed for a given duration of time. To calculate the distance, we use the formula distance = speed × time. Here, the girl cycles at a speed of 5m/s for 3 minutes (180 seconds since 1 minute = 60 seconds). Multiplying her speed by the time gives us,
Distance = 5m/s × 180s = 900 meters.
Therefore, the correct answer to the question is D) 900 m.
