Answer: 0.337 mol Ca
Explanation: 13.5 g Ca ÷ (40.1 g/mol Ca) =
Option B is correct. Average speed can be found through the equation speed = distance/time. Applying this to each person using the data in the chart:
Dennis’ speed: 60 ft/0.5 secs = 120 ft per sec
Johnny’s speed: 60 ft/0.45 secs = 133.333 ft per sec
Travis’ speed: 60 ft/0.52 secs = 115.38 ft per sec
Michael’s speed: 60 ft/0.48 secs = 125 ft per sec
As you can see, Johnny’s speed is the fastest at 133.333 ft/sec.
