<em> 24 mph</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>Vm = 21mph</em>
<em>V1 = 18mph</em>
<em>V2 = ?</em>
<em>Vm = (V₁ + V₂)/2</em>
<em>2Vm = V₁ + V₂</em>
<em>V₂ = 2Vm - V₁</em>
<em>replace Vm ; V₁</em>
<em>V₂ = 2×21mph - 18mph</em>
<em>= 42mph - 18mph</em>
<em>= 24 mph</em>
<em>Good luck !</em>
