You do: 1/2 job/hr
Your friend does: 1/3 job/hr
Together: (1/2 + 1/3) job / hr
= (3/6 + 2/6) job/hr
= 5/6 job/hr .
Since you do 5/6 job/hr, the corresponding
inverse unit rate is
6/5 hr/job
= 1 and 1/5 hr/job
= 1.2 hours/job
= 1 hour 12 minutes per job.
-6, -7, -8 degrees Celsius. I know these temperatures are colder because they are are a higher negative, and when measuring temperature the higher the negative the colder the temperature is.
Hopes that’s what you are looking for!
