Question

The speed limit on a certain highway is 80 kilometers per hour. What is this speed in centimeters per second?

Answer 1

The speed : 2222.2 cm/s

Further explanation

Velocity has magnitude and direction

Can be formulated :

`\tt \boxed{\bold{v=(d)/(t)}}`

v= velocity, m/s

d=distance=m

t=time,s

convert from km/h to cm/s :

`\tt =80(km)/(h)* (10^5~cm)/(1~km)* (1~h)/(3600~s)\\\\=2222.2~(cm)/(s)`
