Answer:
16.197 seconds
Step-by-step explanation:
the time and the final place fot both cars is the same.
for the Boxster we have
<em>X = Vboxster . T</em>
being
X the distancance from the initial place of the Boxter to the meeting point
Vboxster the speed of the Boxster (26m/s)
T the time
and for the Scion
<em>X = Xo + Vscion . T</em>
Being
Xo the initial point of the Scion (115m)
X the distancance from the initial place of the Boxster to the meeting point
Vscion the speed of the Scion (18.9 m/s)
T the time
<em> Xo + Vscion . T = Vboxster . T</em>
<em> Xo = Vboxster . T - Vscion . T </em>
<em> Xo = (Vboxster - Vscion) . T </em>
<em>Xo/(Vboxster - Vscion) = T </em>
<em> 115m/ (26-18.9) m.s-1 = T</em>
<em> 16.197 s = T</em>
