Answer:

 s_{1}  = 600 \: km \\  t_{1}  = 8 \: hr \\  s_{2} = 860 \: km \\  t_{2} = x \: hr  \\  \frac{ s_{1}}{ t_{1}  }  =  \frac{ s_{2}}{ t_{2} } (direct \: proportion) \\  \frac{600}{8}  =  \frac{860}{x}  \\ after \: cross \: multiplying \\ 600 \times x = 8 \times 860 \\ x =  \frac{8 \times 860}{600 }  \\ x =  \frac{172}{15 }  \\ x = 11 \: hr \: 46 \: min
