conversations.value: She meditates for 15 minutes in the morning and 15 minutes at night for a total of 15+15 = 30 minutes
  She meditates 30 minutes daily so in 7 days/1 week she meditates 30*7 = 210 minutes
  She meditates 210 minutes in 1 week so in 4 weeks she meditates 210*4 = 840 minutes
  60 minutes are in an hour so she meditates for 840/60 = 14 hours
  She practices yoga for 1 hour 5 days a week so that's 1*5 = 5 hours
  Over 4 weeks she practices yoga for 4*5 = 20 hours
  She spends 14 hours meditating and 20 hours practicing yoga for a total of 14+20 = 34 hours
