Answer 2

Diameter of wheel = 14 cm

⇒ Radius = ½(14 cm) = 7 cm

We know, circumference = 2πr

{Assume that π = 22/7}

∴ Distance covered in one revolution = 2 × 22/7 × 7 cm = 44 cm

Total distance covered in 3000 revolutions = 44 cm × 3000 = 132000 cm = 1320 m.

Or, speed = (1320 m) × (60 s)^-1 = 22 m/s

{v = s/t}
