Problema Solution
Subway drivers have to start their trains slowing down 1/4 of a mile before the next station. The next station is 5/12 of a mile ahead. Is it time to start slowing down?
Answer provided by our tutors
getting a feel for how much further the train must begin to stop, subtract 1/4 from 5/12:
(5/12)-(1/4)(3/3)
1/6
So the driver can still travel up to 1/6 mile before they must begin to slow down.
