Answer 1

Vishal might be the fastest one

Answer 2

Answer:

Ethan can blow 15 ballons in 20 min.

Rate of Ethan = $\frac {15} {20}$ = 0.75 balloons/min

June can blow 18 ballons in 25 min.

Rate of June = $\frac {18} {25}$ = 0.72 balloons/min

Vishal can blow 16 ballons in 21 min.

Rate of Vishal = $\frac {16} {21}$ = 0.76 balloons/min

Vishal can blow balloons at fastest rate.
