Vedclass · Answer

(B) The office opens at $10 \, AM$ and closes at $5 \, PM$. Total duration $= 5 \, PM - 10 \, AM = 7 \, 	ext{hours}$. Since $1 \, 	ext{hour} = 60 \, 	ext{minutes}$, total office hours $= 7 	imes 60 = 420 \, 	ext{minutes}$. The lunch interval is $30 \, 	ext{minutes}$. The ratio of the lunch interval to the total office hours is $30 : 420$. Dividing both sides by $30$, we get $1 : 14$.

An office opens at $10 \, AM$ and closes at $5 \, PM$. The lunch interval is for $30$ minutes. The ratio of the lunch interval to the total office hours is:
