Ethan can blow 15 balloons in 20 minutes, Jun Wei can blow 18 balloons in 27 minutes and Vishal can blow 15 balloons in 21 minutes. Assuming that all balloons are blown at the same size, who can blow balloons at the fastest rate?
Answers
Answer:
Ethan
Step-by-step explanation:
We first calculate the amount of balloons Ethan can blow in a minute. So we divide 20 by 15 = 4/3 So Ethan can blow one balloon in 1 min. and 20 sec.
Than we calculate the amount balloons Jun can blow per minute is 27/18 = 1 min and 30 sec
After we calculate how much balloons Vishal can blow in 21 min, 21/15 = 7/5 = 1 min 36 sec.
We see that the fastest is Ethan
Answer:
Ethan
Step-by-step explanation:
because he can blow 15 balloons in 20 minutes
he can blow 1 balloon in 1.33 min
next jun can blow 18 balloons in 27 min
means he can blow 1 balloon in 1.5 min
next vishal can blow 15 balloons in 21 min
means he can blow 1 balloon in 1.4 min
so Ethan can blow with fastest rate bcz he can blow in less time.
