    Answer: 2 hours and 45 minutes

    Step-by-step explanation:

    162.50-54 = 108.50

    108.50 divided by 15.50 = 7

    there were 7 additional 15 minutes

    7 x 15 = 105

    105 minutes is 1 hour and 45 minutes

    add the first hour to the 1 hour and 45 minutes

    answer is 2 hours and 45 minutes
