A car travels West for 20min at 80km/hr and in direction 45NW at 30km/hr for 6min. Calculate the Total distance covered/ displacement of the car/ average speed/ average velocity.

asked by stanleylasbrey
  1. west =(1/3)hour*80 + (1/10)hr* 30 * cos 45

    north = (1/10)*30 * sin 45

    distance = sqrt(north^2+west^2)

    displacement = distance at angle T north of west where tan T = north/west

    speed = distance/ (1/3+1/10)

    velocity = speed at angle T
