Mary travelled y meters from point A to point B at an average speed of 4 m/s. She continued with her journey from point B to point Cat 3 m/s. At the end of the entire journey, Mary
travelled a total distance of 150 meters.
Given that the time taken to travel from A to B was 30 seconds more than the time taken to
travel from B to C, form an equation in terms of y.
