<human>:  Emery's family decides to travel for a weekend trip. They drive the first 100 miles in 1 hour. They stop at a McDonald's and then continue the rest of the journey for 300 miles. What's the total number of hours they traveled?
<bot>: How many hours did the next 300 miles take? ** If the first 100 miles took one hour, then let's say the next 300 miles took x hours.
How many hours did the next 300 miles take? ** if 100 miles = 1 hour, then 300 miles =x.
How many hours did the next 300 miles take? ** To find the number of hours traveled for the 300 miles, x = 300*1/100
How many hours did the next 300 miles take? ** x= <<3=3>>3 hours.
How many hours did they travel? ** The total number of hours will be 3 +1 = <<3+1=4>>4 hours
