have any chance of doing this efficiently we need to know
min and maximum for each of these quantities
1 velocity
2 distance
3 time
otherwise its just pissing in the wind
velocity - max = 300km /hour
distance input max = 4000 ,
options of distance base is miles/km/meters/feets
timer allows for 7days 23hours ,59mins, 59,sec,. 99 1/100th - before rolling to 0.00
timer base for speed measurments is sec, min, hour,
