5 Type the correct answer in each box.
The speed of a train is 60 miles per hour.
In 2 hours, the train will cover __
than it did in 2 hours.
miles, in 4 hours, the train will cover __
miles. The train cover ___

(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

this answer is !
