45x +40(x+0.5) =270
45x +40x +20 =270
85x = 250
x = 250/85 = 2.94
45 * 2.94 = 132.3 miles
40*(2.94 +0.5) = 40*3.44 = 137.6
2.94 hours

Answer:
25.1 in (nearest tenth)
Step-by-step explanation:
<u>Formula</u>
Circumference = πd (where d is the diameter)
From inspection of the diagram:
⇒ Circumference = 8π
= 25.1 in (nearest tenth)
You would divide the cheetahs distance which is 300 feet by the cheetahs time which is 2.92 seconds
distance÷time
300÷2.92= 102.7 seconds or 103 seconds if you round up
the cheetahs speed is 102.7 seconds or 103 seconds
