Suppose you went for a drive along a long, straight road that runs east-west. Let's define east to be the positive x direction.
From your home, you drive east at 30. mi/hr to your friends house for 20. minutes, then at 48 mi/hr east for 10. minutes to the grocery store. Finally, you drive west at 60. mi/hr without stopping to get home.
How many minutes will it take to drive from the grocery store to your home (at 60. mi/hr)?
Note: Your answer should have the correct number of significant figures
