Question

Henry will take the 4:47 PM train to San Diego. The train is estimated to arrive in San Diego in 4 hours 41 minutes. What is the estimated arrival time?

Answer 1

ANSWER

$9:28\text{ PM}$

EXPLANATION

We want to find the estimated arrival time.

To do this, add 4 hours 41 minutes to the time that Henry will take the train.

First, let us add 41 minutes to the 47 minutes in 4:47:

$\begin{gathered} 41+47 \\ \\ 88\text{ mins} \end{gathered}$

Since 88 minutes is more than the number of minutes in an hour (60 minutes), subtract 60 from 88 minutes, in other words, convert 88 mins to hours and minutes:

$\begin{gathered} 88-60=28\text{ mins} \\ \\ 88\text{ mins}=1\text{ hr }28\text{ mins} \end{gathered}$

Now, add 4 hours to the 4 hours part in 4:47:

$\begin{gathered} 4+4 \\ \\ 8\text{ hrs} \end{gathered}$

Now, add the 1 hr 28 mins to the 8 hrs:

$\begin{gathered} 8:00+1:28 \\ \\ 9:28\text{ PM} \end{gathered}$

Hence, that is the estimated arrival time.
