Answer:
9
Step-by-step explanation:
First figure out the ratio by doing 3/8, which gives you .375. Then, since that is per minute, you do .375 x 24 which gives you 9, since .375 cars go throug in one minute and it is 24 minutes.
If the 5 scores have a mean of 8, then their total sum would be 8*5 = 40
Now if one score if added (let's call this score x), there are 6 scores and the mean changes to 9, thus:
(40 + x)/6 = 9
40 + x = 54
x = 14
