28 days = 4 weeks

339 days = 11 month

14 months = 420 days

8 weeks = 56 days

90 days = 3 months

3 minutes = 90 seconds

3 days = 72 hours

48 days = 48 days

5 minutes = 300 seconds

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
