To travel from New Orleans to New York, Sue took 3/4 * 24 hours = <<3/4*24=18>>18 hours.
If she stayed in New York for 16 hours, Sue's total time to travel from New Orleans to San Francisco is: 18 hours from New Orleans to New York + 16 hours in New York + 24 hours from New York to San Francisco = <<18+16+24=58>>58 hours.
