Speed = (Distance covered) / Time Taken
Revolutions per minute = 3000 / 60 = 50 revolutions per second
Distance covered in one revolution = Circumference of wheel
= 2r
= (2 * 22 * 7)/7
= 44 cm = 44/100 = 0.44m
Total distance covered in a second = 0.44 * 50 = 22 meter in a second
so the speed is 22 m/sec
hope u like the answer
good luck
