Part A:

What is speed in cm/s?

Radius=10.5 x 8cm

Time from A to D: 7 sec.

A toy car moves clockwise around a circular track at constant speed, as shown in the scale diagram below. Each box in the diagram is 8 cm on a side and each labeled point is halfway between grid points. A D B If the car takes 7 s to travel from point A to point D, what is its speed in cm/s?A toy car moves clockwise around a circular track at constant speed, as shown in the scale diagram below.
