Answer: The Emerald Bot clicks 3 times in __0.4_ sec

²/₁₅ second per click × 3clicks = ²/₅ sec    

Or  0.1333 × 3 = 0.3999  Round to 0.4

Step-by-step explanation: If its unit rate is 7.5 clicks per second, we can find the time, seconds per click by dividing one second by 7.5 clicks

1/7.5 = 0.13333 seconds per click.  

Multiply that  ²/₁₅ seconds by the 3 clicks to get the time it takes for the 3 clicks.
