Answer:
30:54
Step-by-step explanation:
5:9 x 6 = 30:54
The velocity of the car is the rate of change of distance over time.
The car comes to a complete stop at 12 seconds
The velocity function is given as:
When the car comes to a complete stop, V(t) = 0.
So, we have:
Expand
Factorize
Factor out t - 12
Split
Solve for t
This gives
12 > 4.
Hence, the car comes to a complete stop at 12 seconds
