Decimal 
Dozenal 
Let’s do a simple calculation, 100km over 60 minutes:
1.666 km every minute

2 km every minute

Now lets convert this to seconds:
2.777 meters / second

4 meters / second

Another problem with decimal is the fact that we have an odd half base.
As an example, when we look at a clock, the halfway points between the 5 second increments on their way up to 60 is fractional.
This is one of the problems of having an odd half base.

V initial = 0 m/s

t = 9s

d = 130 m

a = ??

A car from rest accelerates at a steady rate over 9 seconds and reaches a total distance of 130 m.
Determine the acceleration of the car:
