Answer:
2.5 meters per second
Step-by-step explanation:
Given,
The speed of Charlotte = 9 km/h
That is, the distance covered in 1 hour = 9 km,
∵ 1 km = 1000 m
So, the distance covered in 1 hour = 9000 m,
∵ 1 hour = 60 minutes and 1 minute = 60 seconds,
⇒ 1 hours = 3600 seconds,
∴ The distance covered in 3600 seconds = 9000 m,
⇒ Distance covered in 1 second = = 2.5 m,
Hence, his/her speed = 2.5 meters per second
