I think c is the answer.....
The car takes 10.8 seconds to reach a velocity of 42.1 m/s
Explanation:
The motion of the car is at constant acceleration, so we can use the following suvat equation:

where
v is the final velocity of the car
u is its initial velocity
a is the acceleration
t is the time
For the car in this problem, we have:
u = 15.0 m/s
v = 42.1 m/s

Solving for t, we find the time it takes for the car to reach that velocity:
