十兵衛よ、これくらいの簡単な計算、できぬと小学生に笑われてしまうぞ。
Juubei, if you can't even do math as easy as this, you'll be laughed at by elementary school students.
であるか。
Is that so?
時計のアラームが五回鳴るのに五秒かかった。
For a clock's alarm to sound five times, it takes five seconds.
この時計のアラームが十回鳴るには何秒かかる？
How many seconds does it take for this clock's alarm to sound 10 times?
正解はＣの十一・二五じゃ。
The correct (answer) is C: 11.25 seconds
であるか。
Is that so?
アラームが五回鳴る時、それぞれの音の間隔は四回ある。
When an alarm sounds 5 times; there are 4 intervals between each sound.
次の音までの時間は、五割る四は一・二五。
The time until the next sound is 5 divided by 4, (which is) 1.25.
アラームが十回鳴る時、
When the alarm sounds 10 times,
音の間隔は九回だから、
there are nine intervals in the sounds, so
一点二五掛ける九は十一・二五となるのじゃ。
1.25 multiplied by 9 is 11.25.
であるな。
That's so!
