Question

Jenny starts her journey at $4:30$ in the morning. She will take $3$ hours and $30$ minutes to reach her destination. At what time will she reach her destination?

• A. $10:00\text{a.m}.$
• B. $9:30\text{a.m}.$
• C. $10:30\text{a.m}.$
• D. $8:00\text{a.m}.$

Answer 1

The correct option is D $8:00\text{a.m}.$

Given Jenny starts her journey at $4:30\text{a.m.}$ and she takes $3\text{h}$ and $30\text{min}$ to reach her destination.
We know that $1\text{h}=60\text{min}$.
So, $3\text{h}$ and $60\text{min}=60+60+60+30=210\text{min}$.

Let’s do a forward counting of $210\text{min}$. in intervals of $30\text{min}$. starting from $4:30\text{a.m}$.


So, Jenny will reach her destination at $8:00\text{a.m}$.
