Answer:

10m/s

Explanation:

Average speed is the change in distance of a body/object with respect to time. Speed is expressed by the expression;

Speed = [tex]\frac{change\ in\ distance}{change\ in\ time}[/tex]

speed ΔV = ΔS/Δt

ΔV = S₂-S₁/t₂-t₁

given S₂ = 50m, S₁ = 40m, t₂ = 5s, t₁ = 4s

average speed = 50-40/5-4

average speed = 10/1

average speed = 10m/s

average speed of the object is 10m/s
