Which speed is the fastest? A 18 feet in 20 minutes B 90 feet in 2.5 hours C 20 yards in 1.5 hours D 3 2/3 yards in 15 minutes
1 answer:
To solve, put each answer in terms of ft/min. Do this by converting all distances to feet and times to minutes, the dividing feet by minutes. A) 
ft/min. B) To get 2.5 hrs to mins, multiply by 60. 
ft/min. C) To get feet from yards, multiply yards by 3. 
ft/min. D) 
ft/min. Now compare the fractions to determine the largest and fastest is 9/10 ft/min, or A.

Answer:
The graph is attached.
Step-by-step explanation:
The range of this data is the highest value, 22, subtracted by the lowest value, 1: 22-1 = 21.
Using boundaries, the first bar would go from 0.5-3.5; the second from 3.5-6.5; the third from 6.5-9.5; the fourth from 9.5-12.5; the fifth from 12.5-15.5; the sixth from 15.5-18.5; the seventh from 18.5-21.5; and the eighth from 21.5-24.5.
The frequency of the first bar, its height, would be 1; the height of the second bar is 2; the height of the third bar is 3; the height of the fourth bar is 2; the height of the fifth bar is 3; the height of the sixth bar is 1; the height of the seventh bar is 1; and the height of the eighth bar is 1.
