Question

The distance d in meters, that a rabbit runs in s seconds is represented by the equation d=11s. What is the

constant of proportionality (unit rate) of d to s?
A 10 m/s
B 11 m/s
C 1/10 m/s
D 1/11 m/s

Answer 1

D 1/11 m/s

Explanation:

Method 1:

d=11s

the unit is m/s which is d/s

meter is 1 here, and time is 11

so, 1/11 meter per second.

Method 2:

First remove A and C, which is obviously not related

B is obviously too fast for a rabit, and thus the answer is D.
