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
