    90 minutes long

    1 hour, 30 minutes

    Step-by-step explanation:

    The science class begun 1:30pm and ends 3:00pm

    An hour is 60minutes.

    Between 1:30pm and 2:00pm is 30minutes.

    And from 2:00pm to 3:00pm is an hour, that is 60minutes

    We therefore have 30minutes+60 minutes=90 minutes long.

    We can also say an hour, 30 minutes
