The amount of time it takes an ice cube to melt in a glass of lemonade is inversely proportional to the temperature of the lemonade. It takes 30 minutes for an ice cube to melt in a glass of lemonade that is 70 °F. How long does it take an ice cube to melt in a glass of lemonade that is 60 °F?

Respuesta :

35 minutes because:
30*70=2100

2100/60=35
