Answer:
No. it is a little below average.
Explanation:
The average speed is (distance covered) / (time to cover the distance) .
<u>For example:</u>
The average speed for the 'car' part of her trip is
(distance covered in the car) / (time in the car) =
(120 km) / (3 hours) = 40 km per hr.
<u>Answering the question:</u>
Average speed for the whole journey is
(distance covered on the journey) / (time spent on the whole journey) =
(240 + 120 + 3) km / (4 + 3 + 1/2) hours =
363 km / 7.5 hours = <em>48.4 km per hour </em>
