What is the number of 360-degree rotations that Tashi's unicycle wheel made while rolling 50 meters in a straight line without slipping?

(1) The diameter of the unicycle wheel, including the tire, was 0.25 meters.
(2) The unicycle wheel made ten 360-degree rotations per minute.

The OA is A.

I'm really confused by this DS question. Experts, can you explain why A is the correct answer, please? Thanks in advance.
