Question 901672: Mitch can jog to Lynn's place in 12 minutes. Lynn can ride her bike to Mitch's place in 5 minutes. How many minutes will they meet if they start from their place at the same time?

You can put this solution on YOUR website! This might work easier if viewed as a task completion problem instead of a travel uniform rates problem.
Think of the distance between Mitch and Lynn from the place of each as 1 job.
This way, Mitch does this job in 12 minutes and Lynn does this job in 5 minutes. If they start this job at the same time then when do they finish (like doing 1 job working together, when do they meet)?
Rates
Mitch, d/12
Lynn, d/5
Think of d=1, ONE FULL DISTANCE, like one whole job.
RT=1, rate time, 1 job or more generally, RT=D using D to stand for the single distance or a number of or fraction of the single distance.
TIME is the variable.
Let t = unknown time for Mitch and Lynn to do the job of the ONE distance.
Reminder,  is in MINUTES.
