Step-by-step explanation:

$<body bgcolor=yellow><marquee direction="up"><font=purple>$

$\huge\bold\red{Hello !}$

$total \: time \: = 11 \frac{3}{5} min = \frac{58}{5} min \\ cindys \: time = x \\ barbara = 3 \frac{3}{10} \\ donna = 2 \frac{4}{5} \\ nicole = 2 \frac{1}{10} \\ barbara + donna + nicole + x = total \: time \\ \frac{33}{10} + \frac{14}{5} + \frac{21}{10} + x = \frac{58}{5}$

$33 + 28 + 21 + 10x = 116 \\ 82 + 10x = 116 \\ 10x = 116 - 82 \\ 10x = 34 \\ x = \frac{34}{10} \\ x = \frac{17}{5}$

$x = 3 \frac{2}{5} min$
