A clock tower takes 6 seconds to strike 4 o'clock (striking 4 times with equal intervals between strikes). How many seconds will it take to strike 8 o'clock?
14 seconds
At 4 o'clock, there are 3 intervals between the 4 strikes. 6 seconds / 3 intervals = 2 seconds per interval. At 8 o'clock, there are 7 intervals between 8 strikes. 7 intervals × 2 seconds = 14 seconds.
