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

The distance between them is 5km

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`
