A bus leaves a station at 1 P.M., traveling west at an average rate of 44 mi/h. One hour later a second bus leaves the same station, traveling east at a rate of 48 mi/h. At what time will the buses be 274 mi apart?

Question

(44 mi/hr x time) + 44 mi = distance 1.
(48 mi/hr x time) = distance of 2.
Add them together.
(44 x time) + 44 + (48 x time) = d1 + d2.
d1 + d2 = 274 miles.
solve for time.
