Question

David leaves the house to go to school he walks 200m west and 125 m north how far is he from his starting point

Answer 1

David is 235.85 meters away from starting point.

Explanation:

To get the distance David is from starting point, we will apply the Pythagoras theorem.

Let the distance he is away from starting point be x.

`200^(2) +125^(2) =x^(2)`

=>
`40000+15625=x^(2)`

=>
`55625=x^(2)`

x =
`√(55625)`

= 235.85 meters

Therefore, David is 235.85 meters away from starting point.

Note: If you need to round this to nearest whole number, it will be 236 meters.

Answer 2

Answer:235.8

Step-by-step explanation:200²m +125²=55625

c²=55625

c=√55625≈235.8
