Answer:

  10 minutes

Step-by-step explanation:

You want to know how much longer 2/3 hour is than the sum of 1/5 hour and 3/10 hour.

Sum

Each fraction of an hour can be expressed in minutes:

  • 2/3 h = 40 min
  • 1/5 h = 12 min
  • 3/10 h = 18 min

The time difference of interest is ...

  (2/3 - 1/5 -3/10) h = (40 -12 -18) min = 10 min

Jacob spent 10 minutes more reading than doing housework.
