A car drives 40 miles on local roads at 20 mph, and 180 miles on the highway at 60 mph, w Your dinner bill is $25 before tax. Th

Anastasy [175]

Answer and Step-by-step explanation:

$Let's~solve~your~problem!$

Formula :

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

Solving for time:

$Time~taken~to~cover~40~miles~on~local~ roads~= \frac{40}{20} = 2~hours$

$Time~taken~to~cover~180~miles~on~the~highway~=$ $\frac{180}{60}=3~hours$

$Total~Time~=~5~hours$

Solving for distance:

 $Total~Distance=40 + 180 = 220$ 

Average speed:

 $\frac{Total~distance}{Total~time} = \frac{225}{5} = 44~miles~per~hour$

Given a line passes through point (5,8) and the origin, find the equation of the line. y=

SOVA2 [1]

Answer:

y = 8/5x

Step-by-step explanation:

I'm assuming that they're asking for the equation in point-slope form.

The formula is y=mx+b where:

m = slope

b = y intercept

However, the y intercept is just (0,0) so b = 0

To find the slope we already have 2 given points: (0,0) and (5,8)

To find slope you do rise/run and you get 8/5

Substitute the slope & y intercept in the formula:

y = 8/5x

Let me know if I'm wrong!!
