Given parameters:
Displacement = 8km
Velocity = 3.8km/h
Unknown:
time = ?
Solution:
Velocity is displacement divided by time.
Velocity = [tex]\frac{displacement}{time}[/tex]
Displacement = velocity x time
Input the parameters:
8 = 3.8 x time
Time = [tex]\frac{8}{3.8}[/tex] = 2.1s
The time taken is 2.1s
