Answer:

90minutes

Step-by-step explanation:

Let the time taken for passengers to be checked-in be t

Let the number of staff working be w;.

If the time taken for passengers to be checked-in for a flight is inversely proportional to the number of staff working then;

t = kw

when t = 30, w = 5

30 = 5k

k = 30/5

k = 6

to get t when w = 15

t = kw

t = 6(15)

t = 90minutes

Hence it will take 90minutes long

Answer:

V=2c

Step-by-step explanation:

$\\[Looking at the relationship of the numbers in the table, we can see which ones will work right off the bat.]\\[Our first numbers are both zero, so we cant do anything significant there.]\\[Next row, however, we can start doing the process of elimination.]\\\left[\begin{array}{ccc}1&2\\2&4\\3&6\\4&8\\5&10\end{array}\right]\\ \\[After plugging in the formulas to see if they're true, the only one that works every time is V=2c.]\\[That is your answer.]$
