Bart simpson drove at a steady speed along the pacific highway with his mother beside him "have you noticed," he said "that the McDonalds signs seem to be evenly spaced along the side of the road? i wonder how far apart they are" Mrs Simpson glanced at her watch, then counted the number of mcdonalds signs they passed in one minute. What a strange coincidence" exclaimed bart, "when you multiply the number by 10 it is exactly equal to the speed of our car in km/h (kilometers per hour) Assuming that the car is traveling at a constant speed and the minute began and ended midway between the 2 signs, how far is it between one sign and the next? I have the answer, it's 166.67 meters, found by: Suppose they pass 6 signs, so the speed is 60km/h therefore 1km/minute 1km/6signs=0.16(repepater) km try with 8, 10,200, all equals the same in the end. So, my question is, how do i write this algebraically, what is the formal method?
