So we have:
Now we can convert from metres to centimetres, keeping in mind that
So, we find:
The distance is 30 km and the displacement is 22.4 km North East

Explanation:
Radiation is a type of heat transfer wherein there is no need for medium or media through which the heat will flow. Consequently, the radiation waves are able to travel through vacuum. The best observation as evidence to conclude that heat is indeed transferred by radiation is the increase of temperature of the receiving body.
