Final answer:
To calculate the distance the girl traveled, speed is multiplied by time which is 40 km/h multiplied by 3 hours, resulting in a total distance of 120 kilometers.
Step-by-step explanation:
The student has asked to determine the distance traveled when a girl cycles for 3 hours at a speed of 40 km/h. To calculate the distance, the formula distance = speed × time is used. In this case, the girl's speed is 40 km/h and the time is 3 hours.
To find the distance:
- Multiply the speed by the time: 40 km/h × 3 h = 120 km.
Therefore, the distance the girl traveled is 120 kilometers.
