Question

how much is 3 hours 12 minutes more than 1 hours 40 minutes​

Answer 1

Difference between 3 hrs 12 minutes and 1 hr 40 minutes

3 hrs 12 min = 3 + 12/60

= 3 + 1/5 = 16/5

1 hr 40 min = 1 + 40/60

= 1 + 2/3 = 5/3

Then,

16/5 - 5/3

=( 48 - 25)15

= 23/15 hrs

= (23/15) *60 min

= 23*4 = 92 min

Therefore 3 hr 12 min more than 1 hr 40 min by 92 min or 1 hr 32 min

hope its help you

Answer 2

Answer:

1 hour 32 minutes

Step-by-step explanation:

As we all know that 1 hour = 60 minutes

So, 3 hours 12 minutes = (3 × 60) + 12

= 180 + 12 = 192 minutes

Similarly, 1 hour 40 minutes = (1 × 60) + 40

= 60 + 40 = 100 minutes

Now, subtract 100 minutes from 192 minutes

192 – 100 = 92 minutes

Now, convert 92 minutes into hours

92 – 60 minutes = 32 minutes

So, the answer is 1 hour 32 minutes
