Question

calculate the speed and velocity of A to B 60m 6s, B to C 40m 4s, A to C 70m. ​

Answer 1

Answer:

10m/s and 70m/s

Explanation:

speed = total distance travelled / total time taken

          = 60 + 40 /6 + 4

          = 10 m/s

Velocity = total displacement / total time

              = 70 / 10

               =  7 m/s

Answer 2

Speed = $\frac{Distance}{Time }$

Velocity = $\frac{Displacement}{Time}$

Speed= $\frac{60+40+70}{6+4}$

           = 17m/s

Velocity = 0m/s because there is no displacement as the starting point and ending point is complete.
