A vehicle leaves a skid mark of 40 ft before stopping. What has the approximate speed of the vehicle before it stopped?
(the formula is speed=.7 times length, then find the square root times 5.5)

Is is 25-35 mph?

  • math -

    40 x .7 = 28
    sq root of 28 is 5.291502622
    multipy that by 5.5 = 29.10326442mph
