Relating increament of speed to time

  1. Nov 24, 2012 #1
    Aditya rides a bicycle from town P to town Q with a constant speed. If he increases his speed by 3 m/s, he will arrive to town Q three times faster. How many times faster will Aditya arrive to town Q, if he increases his speed by 6 m/s



    s=[itex]\frac{d}{t}[/itex]



    Let his constant speed be x
    x= d/t
    Therefore x+3 = (d/t) +3

    if the new speed, x+3, is 3 times faster,

    that means it must be 3x :wink:
