How many days will it take you to cycle to the centre of Earth if you cycle 8 hours a day at 20km an hour?

To reach the center of the Earth, you would need to travel approximately 6,371 kilometers, which is the average radius of the Earth. Cycling at 20 km/h for 8 hours a day means you would cover 160 km daily. Dividing the total distance by your daily travel distance, it would take about 40 days to cycle to the center of the Earth. However, this is purely a theoretical calculation, as cycling through the Earth is not physically possible.
