i need a step by step detail on how to get part b*thank you so much!b) calculate thw magnitude (in km/h) and direction (in degrees north of east) of the hikers average velocity during the given time.

A hiker walks 1 80 km north and then 2.75 km east, all in 2.80 hours. HINT (a) Calculate the magnitude (In km) and direction (in degrees north of east) of the hiker's displacement during the given time. magnitude 3.20 kim direction 33.2 north of east (b) Calculate the magnitude (In km/h) and direction (In degrees north of east) of the hiker's average velocity during the given time. magnitude km/h direction north of east (c) What was her average speed (In km/h) during the same time interval? 1.63 km/h Need Help?
