A bus departs at 8:23 am and arrives at its destination at 11:47 am.
How long was the bus journey?
\(A\)
\(\text{Method 1: Break into steps}\)
\(\rightarrow\text{From 8:23 am to 9:00 am: }\ 60-23 = 37 \text{ minutes} \)
\(\rightarrow\text{From 9:00 am to 11:47 am: }\ 2\ \text{hours}\ 47 \text{ minutes} \)
\(\rightarrow\text{Total: }\ 37 \text{ minutes} + 2\ \text{hours}+\ 47 \text{ minutes}=2\ \text{hours}\ 84\ \text{minutes}\)
\(=3\ \text{hours}\ 24\ \text{minutes}\)
\(\text{Method 2: Calculate hours and minutes separately}\)
\(\rightarrow\text{Hours: } \ 11-8 = 3 \text{ hours} \)
\(\rightarrow\text{Minutes: }\ 47-23 = 24 \text{ minutes} \)
\(\rightarrow\text{Total: }\ 3 \text{ hours } 24 \text{ minutes} \)
\(\Rightarrow B\)
