an activity of 8 minutes each is to be performed by 5 students of class one after the other. the activity starts at 11:10 am with a break of 1 minute between two consecutive activities. when would the activity finish?

11:54 a.m

Step-by-step explanation:

Given that:

Length of activity = 8 minutes

Number of students = 5

Nreak length between each consecutive activity = 1 minutes

Start time = 11:10 a.m

Total activity time = Length of activity * number of students = (8 * 5) = 40 minutes

Total. Break time = 1 + 1 + 1 + 1 = 4 minutes

Total length of activity = (40 + 4) = 44 minutes

11:10 a.m + 44 minutes = 11:54 a.m

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
