A , because you have to divide it so you can get the correct answer
Answer:
See below
Step-by-step explanation:
<u>Given relationship:</u>
a) r = 3, d = 4
- t = d/r = 4/3 h = 1 h 20 min
b) d = 4 miles, rate = r
- t = 4/r, domain is r and must be greater than zero
c) d = 4 miles, time = t
- r = d/t = 4/t, domain is t and it must be greater than zero
d) t = 3 h, rate = r
- d = rt = 3r, domain is r and can be anything greater than zero

You can never have a negative variable, meaning you have to divide by -1 on both sides.
Therefore, the answer would be...
x< 3
You reverse the inequality symbol because you are dividing by a negative number
Hope this helps
