Keiko is choosing between two exercise routines. In Routine #1, she does only running, burning 10.5 calories per minute. In Routine #2, she burns 18 calories walking. She then runs at a rate that burns 8.25 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. O O OSO G
