question_answer 7)

Each mile of railway track required between 1,760 and 2,000 sleepers. If one average sized tree yields 3 to 5 sleepers for a 3 metre wide broad gauge track, calculate approximately how many trees would have to be cut to lay one mile of track.

Answer:

Answer Average number of sleepers required per mile =   1760 + 2000                                                                                                                     2                                                                                                      = 1880 sleepers   Average number of sleepers obtained from one tree = 4                                                                                                Therefore, approximate number of trees to be cut =1880 = 470 trees.                                                                                                     4
