Question

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.​

HI,

ok i will answer but please mark me as brainliest and follow me too!

Explanation:

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.
