ELI5: Why does it take 55 minutes to cook a burrito in the oven, but only 3 minutes to cook a burrito in the microwave?

Here's an analogy:   
You have a towel you are trying to dampen. You can mist it with a spray bottle, or you can dunk it in water. Obviously dunking it will have a much quicker effect, as you are introducing the towel into a saturating wet environment, instead of achieving a wet towel with gradual water, which will take longer.   
Microwaves are completely saturated environments, where as ovens heat food up by warming from the outside, in. There is no way for oven heat to reach the inside of the burrito in 5 minutes, but in the microwave, the microwaves penetrate all the food, immediately.
