Dear Folks –

21.5 billion kilometres. In 2 weeks. The sort of numbers NASA would, literally, kill for.  ;-)

Can someone please cross-check my maths? (And someone online work out the distance from the Sun to Pluto?)  ;-)

Part 1    s = ut + 0.5at^2               

              u            0           

              t             2            weeks

                             14          days

                             336        hours

                             20160   minutes

                             1209600             seconds

              half       0.5        

              a            9.8         m.s^2

              t^2         1463132160000              

              s             7,169,347,584,000         metres

                             7,169,347,584 kilometres

Part 2    v = u + at                          

                             11,854,080        metres per second

                             11,854                kilometers per second

                             42,674,688        kilometers per hour

                             1,024,192,512 km/day

                             7,169,347,584 km/week

Part 3    Reverse (i.e. same distance) as in Part 1                            

                             7,169,347,584 kilometres

TOTAL                 21,508,042,752              kilometers
