    1 minute and 52.5 seconds

    Step-by-step explanation:

    4 Laps = 7 mins 30 sec, we know that there are 60 seconds in a minute so 30/60 = 0.5 plus the 7 minutes we obtain: 7+0.5=7.5 minutes.

    Since we want to find out how many seconds it took to go around once and we know that it took 7.5 minutes to go around 4 times we divide 7.5 minutes by 4 laps and so:

    7.5minutes/4laps = 1.875 minutes so 1 minute and 87.5 % of a minute so:

    0.875 x 60 = 52.5 seconds so 1 minute and 52.5 seconds
