Journey
The Engine stopped for 14m..34s between the Time of finishing the first Journey and starting out upon the Second and as the time of perfoundly the whole Journey of 70 Miles was 6H..23m..31s and the Fuel consumed in that Time was 1127 Pound.
Consequently 1127 x 14m..34s = 42 lbs for the Coke that was consumed between the two Journies.
6..23m..31s
1127 – 42 = 1085 Pounds of Coke consumed for a 70 Mile Journey & 1085/70 = 15.5 Pounds of Coke consumed per mile.
15.5/6.7 = 2.31 lbs of Coke to take a ton of Goods one mile.
2 ½ lbs of Coal will make one pound of Coke.
2.31 X 2.5 = 5.77 Pounds of Coal reqd. to make 2.31 Pounds of Coke.
