Answer:
175 minutes
Step-by-step explanation:
Add up the 8 different times then divide by 4 to get the average driving time for 1 day:
⇒ 12 + 18 + 13 + 21 + 15 + 22 + 15 + 22 = 138
⇒ 138 ÷ 4 = 34.5 mins
Now multiply the average drive time for 1 day by 5 to determine the time taken to drive to and from school for 5 days:
⇒ 34.5 x 5 = 172.5 minutes
As 172.5 ≈ 175 minutes, the nest response is 175 minutes
B is the answer
Because A and C could not be since the set have 4 results
D could not be because f(4)=. 12-5=7 not -7
N = number
n; n+2 (odd)
n(n+2) = 195
n^2 + 2n - 195 = 0
(n-13)(n+15)
n1 = 13 ; n2 = -15 (void)
13; 15 are the two odd integers
