A car drives 30 m north in 1.5 seconds and drives 60 east in 2 seconds. What is the average velocity

19.2 m/s

Explanation:

From the question,

Velocity = displacement/time = d/t

V = d/t Equation 1

Average velocity = Total displacement/ total time

Total dispalcement = √(30²+60²) = √4500 = 67.08 m

Total time = 1.5+2 = 3.5 s.

Substitute these value into equation 1

V = 67.08/3.5

V = 19.2 m/s.

Hence the average velocity is 19.2 m/s
