towards east. What is the total distance travelled and his resultant displace

Answer 1

Answer:

4.5m

5.0m

+1.5m

=11m

Explanation:

This is correct answer

Answer 2

Answer:

Total Distance = 11 m Displacement = 27

Explanation:

Distance = 4.5 +1.5 +1.5

Displacement = √[(4.5)2 x ((4.5+1.5))2]

                       = √[(4.5)2 x (6)2]

                       = √(20.25 x 36)

                       =√729

                       =27
