There is no "as a rule". Different countries - and even different cities within the same country - have different speed limits.
In the UK, speed limits are typically measured in miles per hour (mph). However, some signs may also display speed limits in kilometers per hour (kph) to cater to international drivers.
The speed of light in a vacuum is approximately 670,616,629 miles per hour.
Driving at 751 miles per hour is not physically possible with current technology or speed limits. The fastest land vehicles, like fighter jets, can't reach these speeds. If it were possible, driving at 751 miles per hour would cover 751 miles in 1 hour.
Mph stands for miles per hour; the distance traveled in an hour.

I doubt many people could walk the speed limit. Maybe in a school zone where the limit is 15 miles per hour. However, since the speed limit is a maximum, it doesn't matter.
the sign that says speed limit and that has a number with mph [miles per hour] on it ex:speed limit 50 mph.
That depends what the speed limits are in the area in question.
