In Routine #1, he burns 22 calories walking. He then runs at a rate that burns 15.5 calories per minute.
In Routine #2, he burns 48 calories walking. He then runs at a rate that burns 10.3 calories per minute.
For what amounts of time spent running will Routine #1 burn fewer calories than Routine #2?
