First you find how many prizes were dolls. Then you subtract that number from 64.
Using it's concepts, the average speed and the average velocity are given as follows:
- Average speed: 40 miles per hour.
- Average velocity: 0 miles per hour.
<h3>Average speed</h3>
The average speed is given by the quotient between the total distance traveled and the time taken, that is:
Average speed = total distance/time
In this problem, the total distance is of 60 miles(30 miles west + 30 miles south), in a time of 1.5 hours(1 hour west and 0.5 hours south), hence the average speed is given as follows:
Average speed = 60/1.5 = 40 miles per hour.
<h3>Average velocity</h3>
The average velocity is given by the quotient between the displacement and the time taken, that is:
Average velocity = displacement/time
The displacement is the difference between the final position and the initial position. Since the person got back to the start, finish = start, hence the displacement is of zero, as is the average velocity.
