$Departure \: time \: of \: the \: bus = 7:50 p.m. = 1950 \: hours$

$Time \: interval \: from \: 7:50 p.m. \: to \: 12 \: midnight = \\ = 2400 \: hours \: - 1950 \: hours$

$∴Time \: interval \: from \: 7:50 p.m. \: to \: 12 \: midnight \: is \: 4 \: hrs \: 10 \: min.$

$Time \: interval \: from \: 12 \: midnight \: to \: 5:30 \: a.m. \: the \: next \: day = 5hrs \: 30min$

$∴Total \: time \: taken = 4hrs \: 10min \: + 5hrs \: 30min \\ = 9hrs \: 40min$
