Explanation:

Step1: Find the average speed

To find the average speed, we use the formula \( \text{speed} = \frac{\text{distance}}{\text{time}} \). Yesterday, they drove 550 miles in 11 hours. So the speed is \( \frac{550}{11} = 50 \) miles per hour.

Step2: Calculate today's driving time

Today, they drive 200 miles at the same speed. Using the formula \( \text{time} = \frac{\text{distance}}{\text{speed}} \), we substitute the distance (200 miles) and speed (50 miles per hour). So the time is \( \frac{200}{50} = 4 \) hours.
