A footballer in a training session ran 30km north and then change his direction and ran a further 70 km west. He completed his run in 55 minutes. Calculate his average speed and average velocity

(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

w'x is 0.

hope it
