For this case the first thing you should know is the following change of units:
 1Km = 1000m
 We have then:
 250 meters = 0.250 km.
 The number of fences will be given by the quotient between the total length of the route and the spacing between each fence.
 We have then:
 N = (15) / (0.250)
 N = 60
 
 60 fences will be installed throughout the project.
