A freight ship left port and was sailing due West at 24 knots. The steamship Empress Ann sailing due West at 32 knots left the same port 3 hours later. For how many hours had the steamship been traveling when the two ships had traveled exactly the same distance?
Let F be the distance traveled by the freight ship and E be the distance traveled by the steamship. F = 24t E = 32(t - 3); t > 3 because the steamship departed with a 3 hour delay. F and E will become equal when the ships have traveled the same distance. 24t = 32(t - 3) 24t = 32t - 96 8t = 96 t = 12 hours After 12 hours, the ships will have traveled the exact same distance from the port.
