The earth spins or rotates on its axis every day. It takes 24 hours to rotate once on its axis. To calculate the rate of rotation, the circumference of the earth at the equator, which is 25,000 miles, is divided by the total time taken per rotation, which is 24 hours. The value comes to be approximately 1,000 miles per hour or 1,600 km per hour, which is equivalent to covering the distance between Delhi and Mumbai in 52 minutes (approx.)—quite a high speed indeed.
