The final speed of the car is 2) 150 m/s

Explanation:

Since the motion of the car is a uniformly accelerated motion, we can solve the problem by using the following suvat equation:

$v^2-u^2=2as$

where

v is the final velocity

u is the initial velocity

a is the acceleration

s is the distance covered

For the car in this problem, we have

u = 10 m/s

$a=1.5 m/s^2$

s = 7,467 m

Solving for v, we find the final velocity (and speed) of the car:

$v=\sqrt{u^2+2as}=\sqrt{10^2+2(1.5)(7,467)}=150 m/s$
