it obviously depends how fast you can ride a bike and how long you can go without stopping
A long bike ride that is partially uphill be would be considered vigorous physical activity.

It depends on how fast you can ride a bike!
I presume you mean how long will it take for a 12 miles bike ride. It depends on how fast you can bike, if it's uphill or downhill. The average is between 8-13 mph for most people to bike on a 10-speed on the whole. By that measurement, it could take 50-90 minutes or so on the average.
A "century" in bike rides usually means a 100 mile ride (century =100).
Assuming you could ride at a consistent speed of 10 mph and you don't stop, it would take approximately 8,760 hours or 365 days to ride around the Earth. This calculation does not account for factors like elevation changes, terrain, or rest stops.
5/8 of 24 miles is 15 miles.
Water and fruit, like apple or orange
depends a lot on the riding conditions. For me, on road, about 2400.
They ride a bike for 15 mins and 23 seconds before a game
