Answer:

[tex]45\frac{messages}{hour}[/tex]

Step-by-step explanation:

we know that

To find the rate  of text messages per hour, first divide the total messages by the total time in minutes

so

[tex]\frac{9}{12}=0.75\frac{messages}{minute}[/tex]

Convert to messages per hour

Remember that [tex]1\ hour=60\ minutes[/tex]

Multiply by [tex]60[/tex]

[tex]0.75*60=45\frac{messages}{hour}[/tex]
