As a part of your exercise regimen, you walk 2 miles on an indoor track. Then you jog at twice of your walking speed for another 2 miles. If the total time spent walking and jogging is 1 hour, find the walking and jogging rates and show your solution.

SOLUTION:

We'll use the basic Time= Distance/Speed formula.

Let the speed (or walking or jogging rate) be x.

a) 2/x = Walking Rate
b) 2/2x = Jogging Rate
c) 1 hour = Time

So;

2/x + 2/2x =1
6/2x = 1
x = 3
2x = 6

3 is the walking rate.
6 is the jogging rate.[/b]

Hey, what's the big idea?

You haven't stated what your inertial frame is. Without a frame, you cannot judge time and motion since you have not proven whether or not free bodies exist.

I suppose you could make an argument for locality being sufficiently small enough and application trumping derivation for the purposes of the equation.
