Answer:
A) 300 cc
B) 50 seconds
C) Time taken to fully inflate the balloon will decrease to 33.33 seconds.
Step-by-step explanation:
Given that Tom pumps air into the balloon at a rate of 10 cc per second for a total of 30 seconds, then the current volume of air in the balloon is:
[tex]\sf Current\; volume = 10\; cc/s \times 30\; s = 300\; cc[/tex]
To determine the time in seconds it will take Tom to fully inflate the balloon from scratch, we divide the total volume of the balloon (500 cc) by the rate at which Toms pumps the air (10 cc per second):
[tex]\sf Time=\dfrac{500\;cc}{10\;cc/s}=50\;s[/tex]
If Tom increases the pumping rate to 15 cc per second, the time it will now take for him to fully inflate the balloon from scratch will decrease, as he can fill more of the balloon per second:
[tex]\sf Time=\dfrac{500\;cc}{15\;cc/s}=33.33\;s[/tex]
