Part 1: Convert hours into minutes

We know that:
> 1 hour = 60 minutes

So, to convert hours to minutes, multiply the number of hours by 60.

1) 3 hours = 3 × 60 = 180 minutes
2) 5 hours = 5 × 60 = 300 minutes
3) 9 hours = 9 × 60 = 540 minutes
4) 2 hours = 2 × 60 = 120 minutes
5) 10 hours = 10 × 60 = 600 minutes
6) 1 hour = 1 × 60 = 60 minutes
7) 12 hours = 12 × 60 = 720 minutes
8) 7 hours = 7 × 60 = 420 minutes
9) 6 hours = 6 × 60 = 360 minutes
10) 15 hours = 15 × 60 = 900 minutes

Part 2: Convert minutes into seconds

We know that:
> 1 minute = 60 seconds

So, to convert minutes to seconds, multiply the number of minutes by 60.

11) 3 minutes = 3 × 60 = 180 seconds
12) 9 minutes = 9 × 60 = 540 seconds
13) 10 minutes = 10 × 60 = 600 seconds
14) 1 minute = 1 × 60 = 60 seconds
15) 11 minutes = 11 × 60 = 660 seconds
16) 5 minutes = 5 × 60 = 300 seconds
17) 2 minutes = 2 × 60 = 120 seconds
18) 8 minutes = 8 × 60 = 480 seconds
19) 13 minutes = 13 × 60 = 780 seconds
20) 4 minutes = 4 × 60 = 240 seconds
