Q:

help pleaseCharlotte is running at a rate of 9 km per hour.What is Charlotte's speed in meters per second?

Accepted Solution

A:
Charlotte's speed in meters per second is 2.5 meters per second.
What I did:
9 k per hour= (9/60)=per minute
9/60=0.15=15 m/m
0.15/60=0.025
0.025=2.5 m/s.

That is why Charlotte's speed in meters is 2.5 m/s.
