(10C or 25C) Distance Speed Time

Thanks for the interest of this program and the more refine routine.

I have try your program and some procedure not work as expected.

I will use the example from the HP-12C edition to show you.

Example Problem:

Cycling distance is 35.08 km and took 2 hour 2 minute and 15 second

►What is the Average Speed?

►If to take 1 hour 30 minute What is the Average Speed?

►If the speed is 25 km/h How long it take to cover 35.08 km?

35.08 [STO] 1 // Input Distance

0 [STO] 2 // Unknown Speed

2.0215 [STO] 3 // Input Time

⁕[R/S] 17.2172 ≈ 17.2 km/h // Average Speed Result

1.3 [STO] 3 // Change Time Input

⁕[R/S] 23.3867 ≈ 23.4 km/h // Update the Average Speed

25 [STO] 2 // Input new data for Speed

0 [STO] 3 // Unknow Time

⁕[R/S] 1.24 ≈ 1 hour 24 minute // Update Time Result

------------------------------------------------------------
Your routine some data is not intact when input the two
variables and zero on the unknown. When making data
change the answer is wrong.

The first example is to find Speed and when user change

the Time to solve for the new Speed its doesn't work.
