Answer:
56 miles per hour
Step-by-step explanation:
Here we need to find out the average velocity for the whole trip. We will use the formula of average velocity,The trip was 1,750 miles and it took her 31 hours. According to formula:
Average velocity = Net displacement/Total time taken.
Putting the values of displacement and time.
Average velocity = 1750 miles/31 hours
Average velocity = 56.45 miles/hour
Average velocity = 56 miles/hour
Therefore, 56 miles per hour was the average velocity for the trip.
Hope it help!
