    Answer:

    s = 45000 m

    Explanation:

    The displacement covered by a person or an object traveling at a constant speed can be calculated by the following formula:

    s = vt

    where,

    s = displacement = ?

    v = velocity of car = (60 km/h)(1 h/3600 s)(1000 m/1 km) = 16.67 m/s

    t = time taken = (45 min)(60 s/1 min) = 2700 s

    Therefore,

    s = (16.67 m/s)(2700 s)

    s = 45000 m
