Please help me give me correct answer

Answer 1

$spee d \: = \frac{total \: distance \: covered}{total \: time \: taken} \\ \\ using \: the \: above \: formula \: we \: can \: find \: the \: distance \: if \: the \: speed \: and \: time \: are \: known \: and \: we \: can \: calculate \: time \: if \: distance \: and \: speed \: are \: known. \\ \\ as \: speed \: = \frac{distance \: }{time} \\ . \: \: distance = speed \: \times time \\ \\ and \: time \: = \frac{distance}{speed}$
