If a person is traveling at a rate of seventy five miles per hour in a straight line, how far would they travel in three seconds?

  • Physical Science -

    75 *5280 feet/3600 seconds * 3 seconds = 330 feet
    (about 100 meters)

  • Physical Science -

    To solve this problem we shall use the formula that relates distance, speed and time.

    speed = distance/time
    Or, speed*time = distance

    Now, speed = 75miles/hour = 75miles/(60*60)second = 75miles/3600second = 0.020833mile/second

    So, the distance travelled is = (.020833mile/second)*3second
    = 0.062499mile or 0.0625mile
