<PRE><B>Question 976969</B>
by air the distance from city a to city b is 3003 miles less than the distance fron city c to city d if the total of these two distances is 7807 miles find the distance from city c to city d
----------
(b-a) - (d-c) = -3003
(b-a) + (d-c) = 7807
---------------------------
Subtract and solve for (d-c)::
2(d-c) = 10,810
-----
d-c = 5405 miles
