Load the Goat Z - After Outbreak map and activate the No Hunger goat and Casual goat mutators.
With these active, you can't die or lose health in any way so all you have to do is stay in the game long enough to reach the end of day 10. One day is equivalent to 3 minutes of real time so you're looking at 30 minutes for this one.
There's plenty of tasks to do while you wait, I'd recommend going for the 'I am Goat' achievement which requires you to do nothing (or more accurately, act like a goat) for 5 minutes. The guide for that one can be found here:
(guide is for Xbox One version but it's exactly the same)
