Miss Dubois leaves her house at 7:30. First, an elephant takes 15 minutes to cross the road in front of her. Then, there is a traffic jam for 15 minutes (because Ms. Cicerelli's pet monkey jumped out of her car). After that, Ms. Dubois arrives in the parking lot, but has to help Mrs. Smith pick up her spilled enchiladas for 10 minutes. What time does she finally get to walk into school?
8:10
(Ms. Dubois is late and Ms. Cicerelli and Mrs. Smith are both in bad moods because of their crazy mornings)
