Speed, Time and Distance.

Here we delve into the quite abstract concepts of Speed,Time and Distance. Using our dataset and obscuring one of the three elements we can work out any problem in this mathematical scenario and see through investigation how formulae are arrived at. Of course we are working, in many cases here with decimal numbers and this adds a certain rigour to our problem solving.

DISTANCE = TIME X SPEED per HOUR.

TIME = DISTANCE / SPEED per HOUR.

SPEED = DISTANCE / TIME.

Base of 60 for TIME
Bases of 10,100,1000 for DISTANCE.

We also introduce and use calculators/handhelds for these complex calculations.
