Question

Joe and Max shake hands and say goodbye. Joe walks east 0.40 km to a coffee shop, and Max flags a cab and rides north 3.65 km to a bookstore. How fare apart is there destination?

Answer 1

3.67 km

Step-by-step explanation:

Joe distance towards coffee shop is,

`OB=0.40 km`

And the Max distance towards bookstore is,

`OA=3.65 km`

Now the distance between the Joy and Max will be,

By applying pythagorus theorem,

`AB=\sqrt{OB^(2)+OA^(2)}`

Substitute 0.40 km for OB and 3.65 km for OA in the above equation.

`AB=\sqrt{0.40^(2)+3.65^(2)}\\AB=√(13.4825) \\AB=3.67 km`

Therefore the distance between there destination is 3.67 km.
