Answer:
D. 55%
Step-by-step explanation:
The error range ± 9% means that the range is 9% below 62% or 9% above 62%.
The range is:
(62% - 9%) to (62% + 9%)
53% to 71%.
The only answer between 53% and 71% is 55%.
Answers A, B, C are all greater than 71%.

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
7392/6 pluge into colculater you will get 1232
