A person starts driving 3 km east to a store. The person then turns around and travels 1 km west to another store. Finally, the person travels 2 km west

Given:

Initial distance, do = 3 km

Distance, d1 = 1 km

Final distance, d2 = 2 km

Total distance travelled, D = sum of all the distances travelled

= do + d1 + d2

= 3 + 1 + 2

= 6 km.

Total distance travelled, D = 6 km.
