Question

A street that is 130m long is covered in snow. City workers are using a snowplow to clear the street. The snowplow has tires that are 1.3m in diameter. How many times does a tire have to turn in traveling the length of the street

Answer 1

Snowplow need to turn by 32 times.

Step-by-step explanation:

A street that is 130m long is covered in snow.

Length covered in snow = 130 m

The snowplow has tires that are 1.3m in diameter.

Diameter of snowplow = 1.3 m

Perimeter of snowplow = π x 1.3 = 4.084 m

Length covered in snow = Number of turn required x Perimeter of snowplow

130 = Number of turn required x 4.084

Number of turn required = 31.83 ≈ 32

Snowplow need to turn by 32 times.
