Answer:
Δx= 184.12 ft
Step-by-step explanation:
The equation you need to use is velocity as a function of displacement.

v = the speed at which the car is travelling,
and
v_o is the original speed (in this case zero).
The change in x (displacement) is how far the car travels. You will be solving for a (acceleration).

solving we get
a= 12.19
now put this acceleration value into the second case when v= 67mi/h

⇒Δx= 184.12 ft
209 is the answer (if you know how to divide do it)
Answer:
1 1/8
Step-by-step explanation:
2 1/4/2
9/4 divieded by 2/1=9/8
or 1 1/8
