Team infinite dimentions canoed over 15 3/4 miles in 3 hours. what was their average rate of speed per hour

5 1/4 miles per hour

Step-by-step explanation:

Divide 15 3/4 (distance) by 3 (hours) and you get 5 1/4 (or 5.25) miles per one hour

step-by-step explanation:

(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
