Question

A plane takes off at 21 degrees latitude. It flies directly south and lands at -36 degrees latitude. Which expression represents the difference in latitude?

❘-36 - 21❘
-❘21 + 36❘
-❘21❘ + ❘-36❘
❘21 - 36❘

Answer 1

Distance = ❘-36 - 21❘

Explanation:

Given that,

A plane takes off at 21 degrees latitude.

It flies directly south and lands at -36 degrees latitude.

We need to find the expression for the difference in latitude. It can be calculated as follows:

Distance = |-36-21|

= -57

Hence, the correct option is (A).
