By air the distance from city a to city b is 3002 miles less than the distance from city c to city d. if the total of these two distances is 7818 miles, find the distance from city c to city d.
Answer provided by our tutors
let
x = the distance from a to b
y = the distance from c to d
the distance from city a to city b is 3002 miles less than the distance from city c to city d
x = y - 3002
the total of these two distances is 7818 miles
x + y = 7818
by solving the system
x = y - 3002
x + y = 7818
we find
y = 5410 mi
