The speed of the first car was 6 miles/hour
<h3>Further explanation</h3>
Acceleration is rate of change of velocity.


<em>a = acceleration ( m/s² )</em>
<em>v = final velocity ( m/s )</em>
<em>u = initial velocity ( m/s )</em>
<em>t = time taken ( s )</em>
<em>d = distance ( m )</em>
Let us now tackle the problem!
<u>Given:</u>
Distance between two cars = d = 10 miles
Time Taken = t = 1 hour
Distance covered by the first car = d₁ = 2 + d₂
<u>Unknown:</u>
Speed of the first car = v₁ = ?
<u>Solution:</u>
