Converting Time
Example : Rahul took 1 hour 10 minutes to finish his homework. How many minutes did he spend on his homework?
We know that there are 60 minutes in 1 hour
1 hour 10 minutes = 1 hour + 10 minutes 1 hour 10 minutes
= 60 minutes + 10 minutes 1 hour 10 minutes
= 70 minutes
Rahul spent 70 minutes doing his homework.
Example : Sara's father went to to office for 4 hours 30 minutes. Let's see how many minutes are there in 4 hours 30 minutes.
= 4 hours + 30 minutes 1 hour 10 minutes
= 240 minutes + 30 minutes 1 hour 10 minutes
= 270 minutes
Example : Sara went out of the classroom for 6 minutes 30 seconds. Convert this time into seconds
We know that there are 60 seconds In 1 minute
=6 minutes + 30 seconds 1 hour 10 minutes
= 360 seconds + 30 seconds 1 hour 10 minutes
= 390 seconds
