A street that is 229 m long is covered in snow. City workers are using a snowplow to clear the street. The snowplow has tires that are 1.7 m in diameter. How many times does a tire have to turn in traveling the length of the street? Use the value 3.14 for pi. Round your answer to the nearest tenth. Do not round any intermediate steps.

The diameter of the tires of the snowplow is 1.7m. Therefore, their circumference is π* 1.7 = 3.14*1.7 = 5.338m.( the circumference of a circle with radius r and diameter d is 2πr or πd). Then, the ratio of the length of the street to the circumference of the tires of the snowplow is 229/5.338 = 42.89996253 = 42.9 ( on rounding off to the nearest tenth). Therefore, the tires of the snoplow have to turn 42.9 times before covering the length of the street.
