Classical Mechanics Level pending

A cyclist traveling at 5.0 m/s 5.0 \text{ m/s} uniformly accelerates up to 10.0 m/s 10.0 \text{ m/s} in 2.0 s. 2.0 \text{ s.} Each tire of the bike has a 35 cm 35 \text{ cm} radius, and a small pebble is caught in the tread of one tire. Approximately how far around the wheel does the pebble travel during that acceleration for 2 2 seconds?

25 m 25 \text{ m} 30 m 30 \text{ m} 15 m 15 \text{ m} 20 m 20 \text{ m}
