Question

An object moves $18 m$ in the first $3$ seconds and $22$ m in the next $3$ seconds while it travels $14 m$ in the last $3$ seconds. Calculate average speed in m/s.

Open in App

Solution

Given: First 3 seconds: $S_{1} = 18 m$
Second 3 seconds: $S_{2} = 22 m$
Third 3 seconds: $S_{3} = 14 m$

Average speed $= \frac{S_{1} + S_{2} + S_{3}}{9} = \frac{18 + 22 + 14}{9} = 6 m / s$
