    Approximately 28 times

    Step-by-step explanation:

    The tires are circular in shape.

    We first need to find the circumference of the tire and then divide the length of the road by that circumference.

    The circumference of a circle is given as:

    C = πD

    where D = diameter

    The diameter of the tires is 1.7 m. Its circumference is therefore:

    C = π * 1.7 = 5.34 m

    Therefore, the number of times that the tire has to turn in traveling the length of the street is:

    149 / 5.34 = 27.9 ≅ 28
