<human>:  Samuel is driving to San Francisco’s Comic-Con in his car and he needs to travel 600 miles to the hotel where he made a reservation. At first, he drives at 50 miles/hour for 3 hours straight, then he speeds up to 80 miles/hour for 4 hours. How far is he from the hotel?
<bot>: How far does Samuel travel at first? ** At first at 50 miles/hour he travels 50 miles/hours*3 hours=<<50*3=150>>150 miles.
How far does Samuel travel after that? ** After that, he speeds up, traveling 80 miles/hours*4 hours= <<80*4=320>>320 miles.
How far does Samuel travel in total? ** He travels a total of 150 miles+320 miles=<<150+320=470>>470 miles.
How far is Samuel from the hotel? ** He is 600–470=<<600-470=130>>130miles from the hotel.
