Verified answer

9)  jika
     i  = 6 jam  --> x
    a = 6 jam  --> x
 
     1/6 + 1/6 = 1/x
            2/6  = 1/x
                x = 6/2
                   = 3 jam
   
    jawaban pd soal
    i  = 6 jam  --> y
    a = 3 jam  --> y
 
    1/6 + 1/3  = 1/y
    1/6 + 2/6  = 1/y
            3/6   = 1/y
                 y = 6/3
                   = 2 jam
 
    start pukul = 15.24
    berakhir     = 15.24+ 2jam
                      = 17.24
 
10) a  = 6
      U₆ = 192
 
        U₆ = ar⁵
      192 = 6.r⁵
          r⁵ = 32
          r  = 2
 
      S₆ = a(r⁶-1)/(r-1)
           = 6 (2⁶-1)/(2-1)
           = 6 (64-1)
           = 378 cm
