a teacher teaches for 4 hours 35 minutes every day. For how much time will she teach in 25 days
Answers
In 25 days :
we all know that ,
1 Day = 24 Hours
and
1 Hour = 60 minutes
so, according to Question,
first we change 4 hours 35 minutes into minutes because when we solve this type of question , then we try to convert units of number same
and in this quetion we see that ther are 2 types of units .. first is Hours and second is Minutes....
so, 4 hours 35 minutes
4 hours + 35 minutes
→ (4 × 60 ) minutes + 35 minutes ( 1 hour = 60 minutes)
240 minutes + 35 minutes
= 275 minutes
now , a teacher teaches in 1 day = 275 minutes
so ,
In 25 days,
25 days = 275 × 25
= 6875 minutes
now, 6875 ÷ 60 hours = 114 hours 35 minutes
