468 THE METKIC SYSTEM OF 



Example 2— to find the number of miles in 63,000 kilometres : In the same 

 table, in the line for 60 and in the column under 3 is found 39.146. Removing 

 the decimal point three places to the right for the three ciphers in 63,000, we 

 have the answer — 39,146 miles. 



Example 3 — to find the number of miles in 63,740 kilometres : 



For 63,000 kilometres we have -•- 39,146 miles. 



For 740 kilometres we have 459.81 " 



Hence, for 63,740 kilometres we have ^ . • 39,605.81 '' 



which is ihe number of miles required. 



Example 4 — to find the number of miles in 2,746 meters — that is, in 2.746 

 kilometres: In 27 kilometres by the table are 16.777 miles, and in 46 kilometres 

 by the table are 28.583 miles. Hence, in 2.7 kilometres are 1.6777 miles, 



and in .04-6 kilometres are .028583 " 



. and therefore, in 2.746 kilometres are 1.706283 



Or about 1.7063 miles, which is the number required.
