    60 min ------------80 km

    45 min_______(45/60) x 80 = 3/4 x 80 = 60 km

  • 2 years ago

    80 km/hour => 80 km/60 mins

    i.e. 20 km/15 mins...(÷4)

    so, 60 km/45 mins...(x3)

    speed = distance / time

    You might want to look for an easier subject.

  • Distance = Speed * Time

    D = 80 km/hr * 45 minutes

    How many minutes are in an hour? 60

    D = 80 km/hr * (45 minutes / (60 minutes/hour))

    D = 80 km/hr * (45/60) minutes * hour / minutes

    D = 80 km/hr * (3/4) hour

    D = 80 * (3/4) km * hour / hour

    D = 60 km

    The car travels 80 km in 1 hour

    It travels 80(3/4) or 60 km in 45 minutes.
