Answer 1

Step-by-step explanation:

$\red{ \fbox{ \underline{ \underline{ \huge \text{Solution:}}}}} \\ \\ \blue{ \underline{Since, \: speed \: of \: the \: train = \frac{Total \: distance}{Total \: time \: taken}.}} \\ \\ \green{ \therefore{ \underline{Speed \: of \: the \: train = \frac{513 + \frac{420}{1000} }{6}}.}} \\ \\ \green{ \tt: { \implies{ \underline{Speed \: of \: the \: train = \frac{51300 + 42}{100 \times 6} = \frac{513.42}{6} = 85.57}}}} \\ \\ \red{ \therefore{ \underline{Speed \: of \: the \: train \: is \: 85.57 \: \frac{km}{hr.}.}}}$
