I hooe this sill helo you :)

Answer 2

hiii!!!

here's ur answer...

$it \: is \: direct \: proportion \: as \: speed \: remains \: constant \: and \: distance \: is \: increase \: time \: will \: also \: increase \\ \\ as \: we \: know \: in \: direct \: prortion \: \frac{ x1}{y1} = \frac{x1}{y1} \\ \frac{210}{126} = \frac{x2}{168} \\ \\ x2 = \frac{210 \times 168}{126} \\ \\ x2 = 280 \: minutes \\ \\ hence \: it \: will \: take \: 280mins \: to \: cover \: 168km \\ \\ hope \: it \: helps.....$
