<em>v₂ = 55mph</em>
- Step-by-step explanation:
<em>Hi there ! </em>
<em>Velocity formula</em>
<em>v = distance/time = d/t => d = vₓt</em>
<em>v₁ = v₂ - 11</em>
<em>t₁ = 10h</em>
<em>t₂ = 8h</em>
<em>d = v₁ₓt₁ = (v₂ - 11)t₁ </em>
<em>d = v₂t₂</em>
<em>(v₂ - 11)t₁ = v₂t₂</em>
<em>replace t₁ ; t₂</em>
<em>(v₂ - 11)10 = v₂8</em>
<em>10v₂ - 11ₓ10 = 8v₂</em>
<em>10v₂ - 8v₂ = 110</em>
<em>2v₂ = 110</em>
<em>v₂ = 55 mph</em>
<em>Good luck !</em>
