Remember that i²=-1

the conjugate of a+bi is a-bi

so
3-4i
the conjugate is 3+4i

product
(3-4i)(3+4i)
hey, this looks familiar
remember (a-b)(a+b)=a²-b²
so
(3-4i)(3+4i)=(3)²-(4i)²=9-(16i²)=9-16(-1)=9+16=25

the product is 25
it's conjugate is 3+4i

Using the equation of the proportional relationship:

Average rate of speed = 60

Time taken to go 300 miles = 5 hrs

Distance travelled in 2.5 hrs = 150 miles

<h3>What is a Equation of a Proportional Relationship?</h3>

A equation of a proportional relationship models the relationship between two variables, x and y, that has a constant of k. It is expressed as y = kx.

Given the following:

Equation: d = 60t

d = distance in miles

t = time in hours

Average rate of speed for the bus = k = 60

Time (t) it would take to go 300 miles (d):

300 = 60(t)

300/60 = t

t = 5 hours

Distance (d) it would travel in 2.5 hours (t):

d = 60(2.5)

d = 150 miles
