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
