Question

Entry time of dance studio was $10:00\text{AM}$ and Dave's sister reached the dance studio 28 minutes before the entry time then at what time did Dave's sister reach the studio?

• A. $09:32\text{AM}$
• B. $10:28\text{AM}$
• C. $09:05\text{AM}$
• D. $11:22\text{AM}$

Answer 1

The correct option is A $09:32\text{AM}$

Entry time of dance studio = $10:00\text{AM}$
Dave's sister arrives $28$ minutes before the entry time
Therefore, time at which Dave's sister arrives at the dance studio is:

We need to borrow 1 hour from 10 hours to subtract minutes.
$\because 1\text{hour}=60\text{minutes}$
We need to add 60 minutes in 00 minutes.
It will convert 10 hours to 9 hours and 60 minutes.


Therefore, she arrives at the studio at $09:32\text{AM}$
