    134 kilometers or 83 miles.

    Explanation:

    First make all the units equivalent, so

    60 km/h = 60 km/h or 37.28 m/h

    45 m/h = 72.42 km/h or 45 m/h

    50 km/h = 50 km/h or 31.07

    So in one hour the car has gone 60 km or 37.28 m because they travel at 60km/h, which means they get that far in that amount of time.

    In half an hour they get half of 45 miles, because 45 m/h means they get 45 miles in 60 minutes, so in 30 minutes, or half and hour, they are getting half of 45 = 22.5 miles or 36.21 kilometers.

    In 45 minutes they are getting 75% of 50 km because 45 minutes is 75% of an hour. So 75% of 50 is 37.5 km or 23.3 miles.

    Add this all together and get:

    Kilometers:

    60 + 36.21 + 37.5 = 133.71 km

    Miles:

    37.28 + 22.5 + 23.3 = 83.08 m

    133.71 km = 83.08 So it checks out.

    This is approximately 134 km or 83 miles.
