Answer:
Time taken by Jun Wei to blow a balloon = 25/18 = 1 min 38 secs
Time taken by Vishal is 21/16=1 min 31 secs to blow a balloon.
Time taken by Ethan to blow 1 balloon = 20/15= 1 min 33 secs
We know that lesser the time, faster is the rate. Therefore Vishal can blow the balloon at the fastest rate.
