a ship sails from ny to england at 33 mph and a plane starts at the same time at 605 mph.
The plane arrives in england 104 hours less time than the ship.
How far is it from ny to england
:
Let d = dist from NY to England
:
Write a time equation: time = dist/speed
:
Ship time - plane time = 104 hrs
d%2F33 - d%2F605 = 104
:
Multiply equation by 19965 (33*605)
605d - 33d = 19965(104)
:
572d = 2076360
d = 2076360%2F572
d = 3,630 miles
:
:
Check solution in original equation:
3630%2F33 - 3630%2F605 =
110 - 6 = 104 hrs
