Ethen can blow 15 balloons in 20 minutes Jun Wei can blow 18 balloons in 25 minutes and Vishal can blow 16 balloon in 21 minutes. Assuming that all balloons are blown to the same size, Who can blow the balloon at the fastest rate
Answers
1) Ethen can blow 15 balloons in 20 minutes.
Jun Wei can blow 18 balloons in 25 minutes.
Vishal can blow 16 balloon in 21 minutes.
2) Assuming that all balloons are blown to the same size, this question could be solved from considering two perspectives, i.e. either from the time taken by a balloon to be fully blown (lesser the time, faster the rate) or the no. of balloons fully blown in a minute (more the no. of balloons , faster is the rate).
3) First considering it from the perspective of time taken.
Ethen takes (20/15)=1.33 minutes to blow a balloon.
Jun Wei takes (25/18)=1.38 minutes to blow a balloon.
Vishal takes (21/16)=1.31 minutes to blow a balloon.
As said above, lesser the time, faster is the rate. Therefore Vishal can blow the balloon at the fastest rate.
4) To cross check our answer, lets solve it from the perspective of the no. of balloons blown.
Ethen blows (15/20)=0.75 balloon in a minute.
Jun Wei blows (18/25)=0.72 balloon in a minute.
Vishal blows (16/21)=0.76 balloon in a minute.
As said above, more the no. of balloons , faster is the rate. Therefore Vishal can blow the balloon at the fastest rate.
Step-by-step explanation:
Ethan can blow 15 ballons in 20 min.
Rate of Ethan = 15/20 = 0.75 balloons/min
June can blow 18 ballons in 25 min.
Rate of June = 18/25 = 0.72 balloons/min
Vishal can blow 16 ballons in 21 min.
Rate of Vishal = 16/21= 0.76 balloons/min
Vishal can blow balloons at fastest rate.
I hopes it help you♥️♥️
