The block’s average speed : 0.36 m/s

<h3>Further explanation</h3>

Distance is the length traveled by an object within a certain of time .  

Average speed = total distance/total amount of time ,

Can be formulated :

\tt avg.s(speed)=\dfrac{\Delta D}{\Delta t}

ΔD= total distance

Δt= total time

A block is pulled 0.90 m to the right in 2.5 s :

ΔD= total distance = 0.9 m

Δt= total time = 2.5 s

The block’s average speed :

\tt avg.s=\dfrac{0.9}{2.5}=0.36~m/s
