Answer:
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

Step-by-step explanation:
5x3 15
15x3 45
45x3 135
Answer:
4 3/25 = 4.12
7/8 = 0.875
7/15 = 0.467
(x^2-6x+9)(x^2+6x+9) and expand it
-1.4y=2.14-4.2x
y=(2.14-4.2x)/-1.14
y=-1.52+3.68x
y=3.68x-1.52
