Question:
The radius of a bicycle's wheel is 40 centimeters round the wheel every minute to turn a hundred laps through a bridge with a length of 2,512 meters
The radius of a bicycle's wheel is 40 centimeters round the wheel every minute to turn a hundred laps through a bridge with a length of 2,512 meters
Answer:
40 cm = 0.4 m Requires 2512 ÷ (0.4x3.14x100) = 2512 ÷ 125.6 = 20 minutes
