Final answer:
To find the time it took Pedro to reach the lake, we can use the formula for time: time = distance/rate. Solving for distance, we find that the distance is 22 miles. Now we can use the formula for time again to find Pedro's time: time = distance/rate. Therefore, it took Pedro 5.5 hours to reach the lake.
Step-by-step explanation:
To find the time it took Pedro to reach the lake, we can use the formula for time: time = distance/rate. Both Mike and Pedro hiked the same distance, so we can set up the equation: 5.5 = distance/4. Solving for distance, we find that the distance is 22 miles. Now we can use the formula for time again to find Pedro's time: time = distance/rate. Plugging in the values, we get: time = 22/4 = 5.5 hours. Therefore, it took Pedro 5.5 hours to reach the lake.
