65 miles per hour
56 miles per hour northeast
56 miles per hour
45 miles per hour northeast

Answer 1

Answer:

56 miles per hour

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!
