<human>:  Jenna is planning a road trip. She plans on driving the first 200 miles, and her friend will drive the last 100 miles. They plan on taking 2 30-minute breaks. If Jenna drives 50 miles per hour and her friend drives 20 miles per hour, how many hours will they spend on the road trip?
<bot>: How many miles will Jenna drive? ** Jenna will drive 200 miles at a rate of 50 miles per hour, so she will drive for 4 hours.
How many miles will Jenna's friend drive? ** Her friend will drive 100 miles at a rate of 20 miles per hour, so Jenna's friend will drive for 5 hours.
How many minutes will they spend on breaks? ** They will spend a total of 60 minutes on breaks because 30 minutes + 30 minutes = <<30+30=60>>60 minutes.
How many minutes will they spend on breaks? ** Thus, they will spend 1 hour on breaks because there are 60 minutes in an hour.
How many hours will they spend on the road trip? ** The road trip will take a total of 1+4+5 = <<1+4+5=10>>10 hours.
