The speed of the car = 22.25 m/s

<h3>Further explanation</h3>

Given

A distance of 22.75 km

Time = 17.04 minutes

Required

The speed (in m/s)

Solution

Speed is the ratio of distance per time

Can be formulated :

v = d/t  

v= speed, m/s

d=distance=m

t=time,s

Input the value :

\tt v=\dfrac{22.75~km}{17.04~minutes}\times \dfrac{1000~m}{1~km}\times \dfrac{1~minute}{60~second}\\\\v=\boxed{\bold{22.25~m/s}}

Differentiate between <br>expansion of solid and liquid​
MAVERICK [17]

In a liquid, the expansion is a little more than in

solids. The bonds in a liquid are weaker than in a

solid, so as you heat up a liquid, the particles can

move around each other faster and in so doing,

move further apart. Solids and liquids occupy a

'set' volume at a certain temperature.
