Answer:

t2 = 2.8 hours

Step-by-step explanation:

The distance is the same for each velocity.

Formula

d1 = d2

d = r*t

Givens

r1 = 140 miles / hour

t1 = 3.2 hours

r2 = 160 miles / hour

t2 = ?

Equation

r1*t1 = r2 * t2

Solution

140 * 3.2 = 160 * t2

448 = 160* t2

448 / 160 = t2

t2 = 2.8 hours

Answer:

$2$

Step-by-step explanation:

Given:

$-2(1-4x)=3x+8$

Let's distribute the parenthesis

$-2+8x=3x+8$

Let's subtract $-3x$ from both sides

$-2+5x=8$

Let's add $2$ to both sides

$5x=10$

Now, let's divide both sides by $5$ to get $x$ alone

$x=2$
