The London Marathon course is a 26.2-mile (42.195 km) long route that typically takes elite athletes around 2 hours to 2 hours and 10 minutes to complete. A Formula 1 car is designed for high-speed racing on a smooth racetrack, not for navigating through city streets with tight turns, inclines, and other obstacles. Moreover, the London Marathon course is not a continuous straight line, but rather a winding course through the city streets. Therefore, it's not really possible to estimate how long it would take a Formula 1 car to complete the London Marathon course. However, it's safe to say that the car would not be able to complete the course in anywhere near the time it takes elite marathon runners.
The great wall of china is 5500 miles long. The average marathon runner runs at 12 mph. Therefore if you were travelling at 12 mph, it would take you 500 hours. However obviously we cannot maintain 12 mph for 500 hours. The task is impossible because we cannot run for 500 hours.
It depends on the speed at which the runner is travelling.
1 hour to 5 hours.
