What total distance will be covered by traveling at 60 mph for 75 minutes?

75 miles  

Step-by-step explanation:

speed =

60 mph =

You need to make sure you use the right units

75 mins to hours = 75/60 = 1.25 h

60*1.25 = m

m= 75 miles  

(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
