Last Saturday, Nina helped her mother wash their clothes.
They started washing at 7:30 A.M. and finished at 10:30 A.M. How many hours did they wash the clothes? How many minutes?

To find how many hours before she finished:
10:30 AM-7:30 AM=3:00 meaning 3 hours

Conversion:
1 hour=60 minutes

Convert:
[tex]3 hours(\frac{60 minutes}{1 hour})=180 minutes[/tex]

Hope this helps=)
