A person walks first at a constant speed of 4.8 m/s along a straight line from point A to point B and then back along the line from B to A at a constant speed of 3.2 m/s. What is her average speed over the entire trip? Enter a number with two digits behind the decimal point. Hint: Assume the distance between A and B is d. How much distance does the person cover on her trip? How long does it take her to cover this distance?
