Answer 1

Answer: 23) 40 mph

24) yes. 3.18

25) 44.2%

26) 20 - 30 mph

Explanation:

23)
`\frac{\text{stopping distance}}{\text{speed}}\implies (43)/(20)=2.15\qquad (79)/(30)=2.63\qquad \boxed{(126)/(40)=3.15}`

24)
`(251-79)/(79)=\boxed{3.18}\implies \text{Yes. It is a little more than`

25)
`(183-328)/(328)=\large\boxed{-44.2\%}`

26)

`\large\boxed{20-30}:\quad (79-43)/(43)=83.7\%\\\\\\30-40:\quad (126-79)/(79)=59.5\%\\\\\\40-50:\quad (183-126)/(126)=45.2\%\\\\\\50-60:\quad (251-183)/(183)=37.2\%\\\\\\60-70:\quad (328-251)/(251)=30.7\%`

The largest increase is from 20 - 30 mph
