Kevin can travel 23 1/2 miles in 1/4 hour. what is his average speed in miles per hour?

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
