Answer 1

$\textsf{Given : The Concert which Kevin watches ends at 8 : 40 pm}$

$\textsf{We know that :}$

$\bigstar\ \ \boxed{\textsf{According to 24 hour clock time, 8 : 40 pm is 20 : 40 hours}}$

$\textsf{Given : Kevin takes 22 minutes to go from theatre to the train station.}$

$\textsf{So, When kevin reaches the train station, the time will be :}$

$\implies \textsf{[ \ 20 : 40\ hours + 22\ minutes \ ]}$

$\implies \textsf{[ \ 21 : 00\ hours + 2\ minutes \ ]}$

$\implies \textsf{21 : 02\ hours}$

$\textsf{a) From the given options :}$

$\textsf{The time of the earliest train that kevin can catch is 21 : 15}$

$\textsf{So, The earliest possible train that kevin can catch is at 21 : 15 hours}$

$\textsf{b) We know that, Kevin reached the station at 21 : 02 hours}$

$\textsf{But, The earliest possible train that kevin can catch is at 21 : 15 hours }$

$\textsf{So, Kevin has to wait few minutes until the train arrives}$

$\textsf{The waiting time of kevin until the train arrives is :}$

$\implies \mathsf{[ \ 21 : 15 \ hours - 21 : 02 \ hours \ ]}$

$\implies \textsf{13 minutes}$

$\textsf{So, Kevin has to wait 13 minutes at the station to catch the earliest}\\ \textsf{possible train}$
