3 Days 13 Hours. 2 days and 20 hours turns into 68 hours.Take 20 seconds subtract that by 35 seconds. You get 15. 15 is 3/4 of 20. to figure out the other 1/4 you take 68 and multiply that by 1/4 or 0.25. and you get 85 hours or 3 days and 13 hours.

≡ We know that:
⇔ 2 days 20 hours = 68 hours → Gain 20 seconds
⇔ N → Gain 35 seconds

≡ Solution:
⇒ [tex] \frac{68}{N}=\frac{20}{35} [/tex]
⇒ [tex]N=\frac{(68).(35)}{20}[/tex]
⇒ [tex]N=\boxed{119}Hours=\boxed{4}Days\boxed{23}Hours[/tex]
