50, 52, 58, 55, 59, 50

The mean number of mintues it takes Andre to hike a mountain is 54 minutes.

Andre plans to hike the same moutain trail one more day. Estimate the time it will take him to complete the trail for the seventh day. Explain your reasoning.

54

Step-by-step explanation:

I would say it is 54 if you want to keep the mean. Adding all the numbers up you get 324, and dividing it by 6 is 54, the mean, which is said, If you add another 54 to the total and divide by 7, you will get 54, again.
