Question

in 2 days 20 hours a watch gains 20 seconds find how much time the watch will take to gain 35 seconds

Answer 1

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

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