Question

Ms. Russa has to drive 12 miles north from her house to go to work. From work, she goes to

Answer 1

Answer:

$Distance = 15\ miles$

Explanation:

Given

$North = 12\ miles$

$East = 9\ miles$

Required

Distance from her house to the store

If she drive straight from her house to the store, this would form a right angled triangle;

Where the horizontal line would be:

$North = 12\ miles$

And the vertical line;

$East = 9\ miles$

And the required distance would be the hypothenuse of the triangle;

Using Pythagoras, we have:

$Distance^2 = 9^2 + 12^2$

$Distance^2 = 81 + 144$

$Distance^2 = 225$

Take square root of both sides

$Distance = 15\ miles$
