Question 9
Paul walks from A to B at 80 m/min while Mary starts at the same time from B to A at 60 m/min. They meet 120 m from the midpoint of AB. If Paul stops for a break along the way, they would still meet 120 m from the midpoint of AB. How long is the break, in minutes?
Practice interpretation: the break is positive and is taken before they meet; Mary continues walking at her stated speed. Otherwise a break after meeting would not be determined by the meeting point.
