    Answer: The answer is 716.8 km/hr

    Explanation:

    The main idea here is the convert the given units to km and hr. Here's the conversion factors.

    1mi = 1.6km

    1hr = 60min

    We have to multiply 335miles by 1.60km/mi in order to get the answer in km then again we have to multiply 45 minutes by 1hr/60min in order to get the answer in hr.

    The last step is to calculate the speed using the formula : v=d/t

    =537.6km/0.75hr

    =716.8km/hr
