Can someone me make up a integer word problem ( needs to include at least a negative integer in it)

Airplane A carries a package 500 miles West and drops it off at a station after which another airplane carries the same package 450 miles East to the packages drop off point what is the total miles the package went.
-500miles + 450miles = -50miles

When a point travels West this is negative on the integer graph and East is positive.


West  -5     -4       -3        -2        -1         0          1       2      3      4        5 East

Hopes this helps
