A SHIP TRAVELS FROM NEW YORK TO SOUTHAMPTON ENGLAND AT 33 MILES PER HOUR. A PLANE TRAVELING 605 MILES PER HOUR TAKES 104 HOURS LESS TIME TO MAKE THE SAME TRIP. HOW FAR APART ARE THE TWO CITIES?

let the time taken for the ship be t hours
then the time taken by the plane is t104 hours
so 605(t104) = 33t
solve for t, then evaluate 33t
