Daniel is planning a five-day hike along the Applalachian Trail and calculates that 12% of this journey's total time will be dedicated to the crossing of Garfield Ridge. If Daniel plans to hike 6 hours per day, how many minutes will be dedicated to the crossing of Garfield Ridge?

• 389

• 216

• 43.2

• 3.60

Answer explanation

If Daniel plans to hike 6 hours per day for five days, that is a total of 30 hours. Twelve percent of 30 hours is 3.6 hours. Multiply 3.6 hours by 60 to find how many minutes Daniel will dedicate to the crossing of Garfield Ridge.

What comment can be made about her conclusion?

• Her method was reasonable, and her conclusion is valid

• The method was flawed because the sample size was too small

• The method was flawed because the sample was biased
