The point of intersection of the centerline of Elm Road with the centerline of first Street was originally recorded (using a 30-m steel tape) as being at 6 + 71.225. How far from existing sation mark 5 + 00 on first street would a surveyor have to measure along the centerline to reestablish the intersection point when the temperature is -6 degrees celcius and the tape is 29.995 m under standard conditions?.
