A hiker starts from a camp and follows this route on level ground:
• Walks 3km due east.
• Turns left and walks 4km due north.
• Turns left again and walks 3km due west.
(a) Calculate the total distance travelled by the hiker.
(b) Determine the magnitude and the direction of the hiker’s resultant displacement from the camp.
(c) Explain, in not more than three sentences, why the answers to parts (a) and (b) are different even though they describe the same journey.
