Lisa spent 8 minutes on the phone while routing 2 phone calls. In all, how many phone calls does Lisa have to route to spend a total of 12 minutes on the phone? Solve using unit rates.

Each phone call is worth 4 mins.

8mins/2 phone calls= 4 mins per phone call. That is the unit rate.

So 12 mins equal 3 phone calls.
