Answer 2

Given:

`\begin{gathered} \text{Departure time= 6:40pm} \\ \text{Journey time= 3hours 41minutes} \\ \\ \text{Arrival time= departure time + journey time} \end{gathered}`

Hence,

`\begin{gathered} \text{Arrival time= 6:}40pm+3hrs41\min s \\ =9pm\colon81\min s \end{gathered}`

Since 60minutes make 1 hour, then 81minutes is;

`81\text{minutes}=1\text{hour,}21\text{minutes}`

Adding this to the arrival time;

`\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}`

Therefore, the estimated arrival time is 10:21 pm
