ANSWER
[tex]\begin{gathered} \operatorname{Re}d=0.2m\/s \\ Blue=0.3m\/s \end{gathered}[/tex]EXPLANATION
The velocity of a body is given by:
[tex]v=\frac{d}{t}[/tex]where d = displacement
t = time traveled
The red plastic buggy covers 60 cm (0.6 m) in 3 seconds. Therefore, its velocity is:
[tex]\begin{gathered} v=\frac{0.6}{3} \\ v=0.2m\/s \end{gathered}[/tex]The little blue plastic buggy covers 240 cm (2.4 m) in 8 seconds. Therefore, its velocity is:
[tex]\begin{gathered} v=\frac{2.4}{8} \\ v=0.3m\/s \end{gathered}[/tex]
