Question

A Class demonstration started at 11:25 am and lasted for 4 hours 15 minutes. At what time did the demonstration end?​

Answer 1

Given:
-> Start time = 11: 25 am
-> Continued till = 4 hours 15 min

To Find:
-> The end time

Solution:
if we do 4 hours then it goes as follows
11 25

+ 1 hour
12 25
+ 1 hour
13 25
+ 1 hour
14 25
+ 1 hour
= 15 25 or 3 25 pm
now 15 more min added so ,
25 + 15 = 40

Conclusion:
The demonstration ended on 3:40 pm or 15:40 pm.
