Answer:
It will take 29.31 seconds for the Boxster to catch the Scion
Explanation:
Given the data in the question;
lets say Toyota Scion xB is car A and Porsche Boxster convertible is B and Toyota Scion xB is car A
the distance travelled by car A is
x = 
× t
where is the speed of the car and t is time
the distance travelled by car B before reaching car A will be;
x + x₀ = 
× t
Now lets replace x by × t
so
( × t) + x₀ = × t
x₀ = ( × t) - ( × t)
x₀ = t ( - )
t = x₀ / ( - )
so we substitute
t = 170 m / (24.4 - 18.6)
t = 170 / 5.8
t = 29.31 s
Therefore; it will take 29.31 s for the Boxster to catch the Scion
