    Thomas left Miami and drove at a speed of 41 mph. Katherine left 1 hour and 28 minutes later and drove at a speed of 57 mph. How long will it take Katherine to catch up with Thomas?

    Can anyone show me a solution for it..?

    Thomas covered distance in 1hr 28min = 41*(1+28/60)= 41*88/60 M

    Their relative speed: 57-41=16 mph

    Time: (41*88/60)/16 = 41*88/16*60=3.75833 Hrs = 3 hours 45 min 30 seconds
