2980.83 hours reading in a year,

3406.67 hours listening to music in a year,

and 3650 hours listening to podcasts in a year.

Step-by-step explanation:

Let's multiply each activity she does by 14 and take it to a year:

-Reading

R = 14*35 \frac{min}{d} = 490 \frac{min}{d}*\frac{365 d}{1 y}*\frac{1 h}{60 min} = 2980.83 \frac{h}{y}

She spends 2980.83 hours reading in a year.

-Listenign to music:

M = 14*40 \frac{min}{d} = 560 \frac{min}{d}*\frac{365 d}{1 y}*\frac{1 h}{60 min} = 3406.67 \frac{h}{y}  

She spends 3406.67 hours listening to music in a year.

-Listenign to podcasts:

P = 14*1.25*4 \frac{h}{w} = 70 \frac{h}{w}*\frac{1 w}{7 d}*\frac{365 d}{1 y} = 3650 \frac{h}{y}

She spends 3650 hours listening to podcasts in a year.

I hope it helps you!
