Question

Two cars leave the same parking lot, with one heading north and the other heading east. After several minutes, the northbound car has traveled 4 kilometers, and the eastbound car has traveled 3 kilometers. Measured in a straight line, how far apart are the two cars?

Answer 1

Answer:

The distance between them is 5km

Step-by-step explanation:

Given

$Car\ A =4km$

$Car\ B =3km$

Required

Distance between them

The scenario can be represented with the attached image

The distance between them is then calculated using Pythagoras theorem

$d^2 = 4^2 +3^2$

$d^2 = 16 +9$

$d^2 = 25$

Take square roots of both sides

$d = \sqrt{25$

$d = 5$
