Question

Event A starts at $11:25$ a.m. and the duration of the event is $33$ minutes. Event A is followed by Event B. The duration of Event B is $42$ minutes. Find the time at which Event B ends.

• A. $12:40$ p.m.
• B. $11:58$ a.m.
• C. $11:58$ p.m.
• D. $12:40$ a.m.

Answer 1

The correct option is A $12:40$ p.m.

Event A starts at $11:25$ a.m. and the duration of the event is $33$ minutes.

To calculate the end time of Event A, let’s jump 33 minutes from the starting time.
$33$ minutes can be broken down as:
$33min=10+10+10+3$

So, we finally land at $11:58$ a.m.
So, the end time of Event A is $11:58$ a.m.

Given, Event A is followed by Event B.
So, the start time of Event B will be the same as the end time of Event A.
So, the start time of event B will be $11:58$ a.m.
Also, the duration of Event B is 42 minutes.

To calculate the end time of Event B, let’s jump $42$ minutes from the starting time.
$42$ minutes can be broken down as:
$42\text{min}=10+10+10+10+2$


So, we finally land at $12:40$ p.m.
So, the end time of Event B is $12:40$ p.m.
