Answer:
The speed of the cars is 
Step-by-step explanation:
First we must first have the clear concept that
or 
Our question is the speed of the cars then the variable to clear will be s.
Let's raise the equation for each car taking into account that we have the following data:
Car 1:
,
and 
Car 1:
,
and 
The two cars travel the same distance so we will raise the distance formula for each car and then match them.
<em>Car 1</em>



<em>Car 2</em>







The speed of the cars is 32 km/hr
1.65 + 0.85x= $20
0.85x=$18.35
x=21 10/17
first you write the equation
then you have to subtract 1.65 from the equation but you also have to subtract it from 20
then you divide 0.85 from 0.85x and from the 18.35 left over from subtracting 1.65 from 20
then you should get x=21 10/17 (simplified) but the decimal form is a ongoing fraction so you can just round it up to the nearest hundredth
