<human>:  Stuart is going on a cross-country trip and wants to find the fastest route. On one route the total distance is 1500 miles and the average speed is 75 MPH. On the second trip, the total distance is 750 but the average speed is 25 MPH. How long does his trip take if he goes on the fastest route?
<bot>: How many hours will the first route take? ** The first route will take 20 hours because 1,500 / 75 = <<1500/75=20>>20
How many hours will the second route take? ** The second route will take 30 hours because 750 / 25 = <<750/25=30>>30
How many hours will the fastest route take? ** The fastest route takes 20 hours because 20 < 30
