Problema Solution
Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels 12 miles per hour slower than the westbound train. If the two trains are 570 miles apart after 3 hours, what is the rate of the eastbound train?
Answer provided by our tutors
Let 'x' represent the speed of the eastbound train, then 'x+12' represents the speed of the westbound train.
distance = speed * time
3x + 3(x + 12) = 570
