Let's solve the problems presented in the image.

Problem a:

223 minutes + 14 minutes + 34 minutes
We add the minutes: $223 + 14 + 34 = 271 \, \text{minutes}$

Now, convert 271 minutes to hours and minutes:

• There are 60 minutes in an hour. $\frac{271}{60} = 4 \, \text{hours} \, 31 \, \text{minutes}$

Answer for part a:

$271 \, \text{minutes} = 4 \, \text{hours} \, 31 \, \text{minutes}$

Problem b:

61 hours 15 minutes ÷ 5
First, convert the time to only minutes: $61 \, \text{hours} \times 60 = 3660 \, \text{minutes}$ Add the 15 minutes: $3660 + 15 = 3675 \, \text{minutes}$ Now, divide by 5: $\frac{3675}{5} = 735 \, \text{minutes}$ Convert 735 minutes back to hours and minutes: $\frac{735}{60} = 12 \, \text{hours} \, 15 \, \text{minutes}$

Answer for part b:

$61 \, \text{hours} \, 15 \, \text{minutes} \div 5 = 12 \, \text{hours} \, 15 \, \text{minutes}$
