See below

Step-by-step explanation:

Given relationship:

• d = rt

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
