Answer:

6.67km/hr²

Explanation:

Given parameters:

Velocity  = 40km/h

Time  = 6h

Unknown:

Acceleration = ?

Solution:

Acceleration is the rate of change of velocity with time.

  Acceleration  = [tex]\frac{v - u}{t}[/tex]  

v is the final velocity

u is the initial velocity

t is the time

    Acceleration  = [tex]\frac{40 - 0}{6}[/tex]   = 6.67km/hr²
