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.

It would help if you proofread your questions before you posted them.
From your data, all I get is:
15t > 12t, which applies for all values of t.
