Supposing a clock takes 7 seconds to strike, 7.
How long will the same clock take to strike 10?
Answer:
While striking 7 the clock strikes its first gong at 7 o’ clock and it strikes
6 more at regular intervals. These 6 intervals take 7 seconds so that the
interval between gongs is 7/6 seconds. However, to strike 10 there are 9
intervals each taking 7/6 seconds for a total 10 ½ seconds.
