Problema Solution
two trains leave the station at 12:00pm, one heads north at 80mph and the other train heads south at 100mph. at what will they be 540 miles apart?
Answer provided by our tutors
both trains are heading in opposite directions, their relative velocity is then the sum of their velocities:
80 + 100 = 180 mph
540 / 180 = 3
in 3 hours, at 3:00pm, they will be 540 miles apart
