**Reiny**, Monday, January 23, 2012 at 9:42pmnumber of days = 20 hrs / (k/5 hrs/day)

= 20(5/k) days

= 100/k days

testing:

suppose k = 10

is my answer reasonable?

Student would spend 10 hrs a day awake, ok

student would spend 2 hrs a day doing hmwk, ok

so to do a 20 hrs assignment should take 10 days

my formula 100/10 = 10 , ok!!!!
