A woman driving a car 14 ft long is passing a truck 30 ft long. The truck is traveling at 50 mi/h. How fast must the woman drive her car so that she can pass the truck completely in 6s?

  1. (30 + 14)/6 = speed

    Convert from feet per second to mph.

    I hope this helps.

  2. let the speed of car =xmi/h
    relative speed =(x-50)mi/h
    time taken to overtake=1/600h
    s=d/t
    distance to be covered=44/5280mi
    s*t=d
    (x-50)(1/600)=44/5280
    x=55mi/h
