    74miles/hr

    Step-by-step explanation:

    Kevin can travel 23¹/₂ miles in ¹/₄ hour.

    The average speed in miles per hour

    Speed = distance / time

    distance = 23¹/₂ miles = 2x23+1/2 = 46+1/2=47/2

    Time = ¹/₄ hour

    Speed = 23¹/₂ / ¹/₄ = ⁴⁷/₂ / ¹/₄ = ⁴⁷/₂ * ⁴/₁=⁴⁷/₁ * ²/₁ = ⁴⁷*²/₁ = ⁷⁴/₁ = 74miles/hr
