The speed of light is: c = 3x10^8 m/s <span>

or

c = 186,000,000 miles/sec = 1.86x10^8 mi/s

1 furlong = 0.125 mile

1 fortnight = 2 weeks(7d/wk)(24h/d)(3600s/h)
= 1209600s = 1.2096x10^6 s

Therefore,

c =1.86x10^8 mi/s(1furl/0.125mi)(1.2096x10^6s/fort)

<span>c = 18x10^14 furlong/fortnight = 18x10^8 Mfurlong/fortnight</span></span>
