A tour bus normally leaves for its destination at 5:00 p.m. for a 200 mile trip. This week however, the bus leaves at 5:40 p.m.

iren2701 [21]

Answer:

The usually speed of the bus is 50 miles/h.

Step-by-step explanation:

Let the usual speed of the bus be x mile/hour.

We know that

$speed=\frac{distance}{time}$

$\Rightarrow time = \frac{distance}{speed}$

The bus travels 200 miles.

To reach its destination it takes time $=\frac{200}{x}$ h

This week however the bus leaves at 5:40.

The bus late 40 minutes $=\frac{40}{60} h$ $= \frac{2}{3}h$

Now the speed of the bus is = (x+10) miles/h

The new time to reach the destination is $=\frac{200}{x+10}$ h

According to the problem,

$\frac{200}{x}-\frac{200}{x+10}=\frac{2}{3}$

$\Rightarrow 200[\frac{x+10-x}{x(x+10)}]=\frac{2}{3}$

$\Rightarrow 200[\frac{10}{x^2+10x}]=\frac{2}{3}$

⇒2(x²+10x)=200×10×3

⇒x²+10x = 3000

⇒x²+10x -3000=0

⇒x²+60x-50x-3000=0

⇒x(x+60)-50(x+60)=0

⇒(x+60)(x-50)=0

⇒x= -60,50

∴x=50 [since speed does not negative]

The usually speed of the bus is 50 miles/h.

Nathaniel purchases a one year membership pass to an art museum as a member he receives a discounted entrance fee the total cost

Arturiano [62]

For this case, we must find the equation of the line.
The generic equation of the line is:
$y-yo = m (x-xo)
$
The slope of the line is:
$m = \frac{y2-y1}{x2-x1}$
Substituting values we have:
$m = \frac{15-12}{2-0}$
Rewriting:
$m = \frac{3}{2}$
$m = 1.5$
We now choose an ordered pair:
(xo, yo) = (0, 12)
Substituting values we have:
$y-12 = 1.5 (x-0)$
Rewriting the equation:
$y= 1.5x+12$
For 20 visits, we evaluate the equation when x = 20.
We have then:
$y= 1.5(20)+12$
$y= 30+12$
$y= 42$
Answer:
The discounted entrance fee is 1.5$. The total cost is 42$ after 20 visits
