Answer 1

Answer:

a) 1350 minutes

b) 790 minutes

Step-by-step explanation:

a) Firstly, we know that:

1 hour = 60 minutes

So take 10 hours out of 22,

10 hours = (60 x 10) minutes

10 hours = 600 minutes

Thus, you have another 12 hours remaining so take another 10 hours which is another 600 minutes. Finally you have 2 hours remaining.

2 hours = (60 x 2) minutes

2 hours = 120 minutes

To get the total answer, add everything and don't forget the other 30 minutes.

600 + 600 + 120 + 30 = 1350 minutes

b) Like we did before, take out 10 hours

10 hours = 600 minutes

Now we have 3 hours remaining so:

3 hours = (60 x 3) minutes

3 hours = 180 minutes

Add everything together, without forgetting the other 10 minutes.

600 + 180 + 10 = 790 minutes
