How to Add Time - Hours and Minutes?
1. 5 h 31 min + 4 h 49 min = ______ h ______ min
Step 1: Add the minutes.
31 min + 49 min
= 80 min
= 1 h 20 min
Step 2: Add the hours.
5 h + 4 h + 1 h 20 min
= 10 h 20 min
So,
5 h 31 min + 4 h 49 min
= 10 h 20 min
31 min + 49 min
= 80 min
= 1 h 20 min
Step 2: Add the hours.
5 h + 4 h + 1 h 20 min
= 10 h 20 min
So,
5 h 31 min + 4 h 49 min
= 10 h 20 min
2. Alice swam for 38 minutes. She played on the slides for 36 minutes.
How long did she spend on the two activities?
38 min + 36 min
= 74 min
= 60 min + 14 min
= 1 h 14 min
She spent 1 h 14 min on the two activities.
= 74 min
= 60 min + 14 min
= 1 h 14 min
She spent 1 h 14 min on the two activities.
3. Ricky watched 2 h 30 min of TV on Saturday and 3 h 35 min of TV on Sunday.
How much time did he spend watching TV on the two days?
Step 1: Add the minutes.
30 min + 35 min
= 65 min
65 min is more than 60 min. So, regroup the result.
65 min
= 60 min + 5 min
= 1 h 5 min
Step 2: Add the hours.
2 h + 3 h + 1 h 5 min
= 6 h 5 min
He spent 6 h 5 min watching TV on the two days.
30 min + 35 min
= 65 min
65 min is more than 60 min. So, regroup the result.
65 min
= 60 min + 5 min
= 1 h 5 min
Step 2: Add the hours.
2 h + 3 h + 1 h 5 min
= 6 h 5 min
He spent 6 h 5 min watching TV on the two days.
