Diameter of wheels of skateboard = 60 mm
Raidius of wheels of skateboard = 30 mm
Number of revolutions by wheels = 20
Distance travelled by Aliaa = ?
Distance travelled by Aliaa = 20 * circumference of the wheel of skateboard
= 20 * 2 * π * r
= (20 * 2 * 22 * 30)/ 7
= 264/7
= 37.714 mm (approximately)
