Solution:
Given:
[tex]\begin{gathered} \text{Departure time= 6:40pm} \\ \text{Journey time= 3hours 41minutes} \\ \\ \text{Arrival time= departure time + journey time} \end{gathered}[/tex]Hence,
[tex]\begin{gathered} \text{Arrival time= 6:}40pm+3hrs41\min s \\ =9pm\colon81\min s \end{gathered}[/tex]Since 60minutes make 1 hour, then 81minutes is;
[tex]81\text{minutes}=1\text{hour,}21\text{minutes}[/tex]Adding this to the arrival time;
[tex]\begin{gathered} 9pm\colon81\min s=9pm+81\text{minutes}=9pm+1\text{hour 21minutes} \\ =10pm,21\text{minutes} \\ \\ \text{Hence, } \\ \text{The estimated arrival time will be;} \\ 10\colon21pm \end{gathered}[/tex]Therefore, the estimated arrival time is 10:21 pm
