Answer: 2.5 hours

This is equivalent to equivalent to 2 hours, 30 minutes.

======================================================

Work Shown:

1/3 of the house = 50 minutes

3*(1/3 of the house) = 3*(50 minutes)

3/3 of the house = 150 minutes

1 house = 150 minutes

-----------

Sam will need 150 minutes to clean the whole house

Divide this over 60 to convert to hours

150 minutes = (150/60) hours

150 minutes = 2.5 hours which is the final answer

-----------

Or you could say the following

150 minutes = 120 min + 30 min

150 minutes = (120/60) hr + 30 min

150 minutes = 2 hr + 30 min

This shows that 2.5 hours is equivalent to 2 hours, 30 minutes.
