The trip is said to last 3.15 hours. When the train arrives in Madison, the conductor notices it actually took them 3.26 hours. The train company prides itself on always having its train to the station within a 3% error of the expected time. Will the train company live up its regulation on this trip?Alishba wakes up late and runs to school, covering a distance of 2.55 km in a direction of [N200 E] as measured from her home. She then realizes that her friend Lydia has her homework and races over to his house 0.5 km away [W] from the school. The two friends then decide it’s not worth going to class late so they go off to the mall that is 2.8 km [W500 S]. a) What is Alishba’s total displacement? b) If the total time taken by Alishba to run to school then over to the friend’s house was 25 minutes, what was her average velocity?
