Ryan ran a race at a pace of 6 miles per hour. They ran a total of 9 miles. If you solve using the equation 6x=9 , which unit should be used for the missing value? Enter 1 for miles, 2 for hours, or 3 for miles per hour.(1 point)
Based on the equation 6x = 9, which represents the relationship between Ryan's pace in miles per hour (6 miles per hour) and the distance he ran (9 miles), the missing value should have the same units as the remaining value. In this case, since the remaining value is 9 miles, the missing value should also be in miles. Therefore, the correct answer is 1 for miles.
