Answer:


0\text{ feet}

Explanation:

GIVEN: Eve takes a subway train to work that travels at an average elevation of
-14 feet. Jacob takes a bus to work that travels at an average elevation
14 feet higher than eves train.

TO FIND: Average elevation the bus travels at.

SOLUTION:

Average elevation of subway train
=-14\text{ feet}

Now,

Jacob takes a bus to work that travels at an average elevation
14\text{ feet} higher than that of subway train.

Average elevation of bus
=\text{Average elevation of subway train}+14

putting the value

Average elevation of bus
=14+(-14)


=14-14=0\text{ feet}

Hence the average elevation at which the bus travels at is
0 feet or ground level.
