A turtle moves 3.5m [E] in 136 s and then moves 1.7m [W] in 88 s.

Question

a) What is the average speed of the turtle?

b) What is the average velocity of the turtle?

average speed:

D/T
= 3.5m + 1.7m = 5.2m/ 224s
= 0.024m/s

average velocity:??????????

Have I calculated speed correctly?

Answer 1

speed is correct.

avg velocity=dislacement/time
= (3.5E+1.7W)/time= 1.8m/224s East

Answer 2

Thanks bobpursley.

Answer 3

would the answer be 0.008 or 0.0080m/s [E]?

Answer 4

Velocity needs both Magnitude (speed) AND Direction.
