Answer 2

➨The purpose of the Royal Observatory was a practical one: to reduce shipwrecks. At that time mariners had no accurate way of working out their position when out of sight of land. They could find their latitude (north-south position) by observing the sun or stars, but not their longitude (east-west position).
