The wheel of a motorcycle is of radius 35 cm. How manyrevolutions per minute must the wheel make so as to keep aspeed of 66 km/hr? plss help!
Answered by admin @
Hiii. It's jeeta here. Any doubt you can ask to me. For this question the correct answer is 500 revolutions. Now we will see how?? The circumference of circle is 2πr. Using this we get to know that circumference is 220 cm. Now the distance covered in one minute is 6600000/60=110000cm per minute. Total number of revolution to maintain the same speed is110000/220=500 revolution. Hope it helps. Please rate my answer
