Step-by-step explanation:

$given: \\ speed(v) \: between \: a \: and \: b = 540km {h}^{ - 1} \\ distance(s) = \frac{velocity(v)}{time(t)} \\ s = \frac{540}{1} \\ total(s) = 540km \\ \\ speed \: of \: a \: (v1) = 40km {h}^{ - 1} \\ speed \: of \: b \: (v2) = 50km {h}^{ - 1} \\ \\ distance \: travelled \: by \: a \: in \: 1hr = 40km \\ distance \: travelled \: by \: b \: in \: 1hr = 50km \\ adding \: both \: distances = 40 + 50 = 90km \\ time = \frac{total \: distance}{distance \: travelled \: by \: a \: and \: b } \\ t = \frac{540}{90} \\ t = 6 \: hours$
