Answer:

t=-10 or t=20

Step-by-step explanation:

We want to solve the equation:

$|3t - 15| = 45$

We use the definition of the absolute value function to get:

$- (3t - 15) = 45 \: or \: (3t - 15) = 45$

Divide through the first equation by -1 to get:

$3t - 15 = - 45 \: or \: 3t - 15 =45$

We now add 15 to both sides of the equation to get:

$3t = - 45 + 15 \: or \: 3t =45 + 15$

$3t = - 30 \: or \: 3t =60$

Divide through by 3

$t = - 10 \: or \: t = 20$

27 pages/4.5 mins = 324/n

Now, solve for n.

N=54

So, 54 minutes is the answer!
