I'll give you a question, please answer with step-by-step reasoning process.
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?

4
If the first 100 miles took one hour, then let's say the next 300 miles took x hours.

if 100 miles = 1 hour, then 300 miles = x.

To find the number of hours traveled for the 300 miles, x = 300 * 1 / 100.

x = 3 hours.

The total number of hours will be 3 + 1 = 4 hours.

.

The final answer: 4
