    first of all I appreciate your work I have a question: what if we have to times and to speeds with different direction? how can we get the average velocity? thanks..

    opps!! you forgot the direction of the avg. velocity :) V avg. = 1.39 m/s north

    we should say displacement as 's' because distance is known as 'd'

    why can't we say 1.39 as 1.4 m/s when calculated? and round off and 1 m/s?
