Answer 2

Answer:

2 hours and 35 minutes

Step-by-step explanation:

$\implies \texttt{Distance} = 51km \\\\\texttt{Time Taken} = 45 \ minutes\\\\\texttt{Speed} = \frac{distance}{time} = \frac{51}{45} \\\\ \textsf{Now, distance = 221km}\\\\ \implies \textsf{speed =}\frac{51}{45} \\\\ \textsf{Now, time taken will be equal to the distance divided by speed.} \\\\ \textsf{So, time taken =} \frac{221}{\frac{51}{45} } \\\\ \implies 195 \ minutes \ or \ 2 \ hours, \ 35 \ minutes$
