The distance d, in meters, that a rhinoceros runs in s seconds is represented by the equation d=16s. What is the constant of pro
castortr0y [4]
Time          Distance                Distance / Time
2hrs          90 miles                  90 miles / 2 hrs =  45 miles / hr
3hrs          135 miles                135 miles / 3 hrs =  45 miles / hr
5hrs          225 miles                 225 miles / 5 hrs =  45 miles / hr
6hrs          270 miles                  270 miles / 6 hrs =  45 miles / hr

Constant of proportionality is 45 miles / hr. This is the same for the four values. The unit rate is also 45 miles / hr.

Let us assume the Distance , d is directly proportional to Time, t
d α t
d = kt 
Constant of proportionality is k which is D/T
d = 45t

What is the relationship between the segments PQ and P’Q’
cupoosta [38]

Answer:

\frac{PQ}{P'Q'}=2.5

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal

In this problem Triangles OQP and OQ'P' are similar by AA Similarity Postulate

so

\frac{PQ}{P'Q'}=\frac{OP}{OP'}

we have

OP=12-2=10\ units

OP'=6-2=4\ units

substitute

\frac{PQ}{P'Q'}=\frac{10}{4}=2.5
