Answer 2

Answer:

$total \: time \: taken = (45 + 5) \: min = 50 \: min = \frac{5}{6}hr \\ total \: distance \: travelled = \: average \: speed \times total \: time = 72 \frac{5}{6} = 60 \: km \\ since \: ms \: verma \: drove \: 15 \: km \: distance \: that \: ms \: verma \: drove = 60km - 15 \: km = 45 \: km$
