Answer 1

Answer: Magnitude of displacement in 2 hr = √[4² + 3²] = 5 km

Average velocity = 5/2 = 2.5 km/hr in the direction making an angle θ with north towards east given by  

θ = tan^-1 (3/4) = 36.87 or 37 degree east of north  

So final answer: average velocity 2.5 km /h 37 degree east of north.

its correct....plz mark it as brainlist.
