Miguel is choosing between two exercise routines.
In Routine #1, he does only running, burning 15 calories per minute.
In Routine #2, he burns 12 calories walking. He then runs at a rate that burns 12 calories per minute.
For what amounts of time spent running will Routine #1 burn more calories than Routine #2? Use t for the number of minutes spent running, and solve your inequality for t.

Amt = 15t
routine #2 = 12 + 12t
15t > 12+12t
easy to solve
