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
We need to compare 1/4 and 5/12.
Since 1/4 = (1*3)/(4*3) = 3/12 and 5/12 > 3/12 follows it is still not time to start slowing down.
