The number of minutes Samantha needs to run on Friday to reach her goal is 45 minutes.

<h3>Average</h3>

Monday = 45 minutes
Tuesday = 30 minutes
Wednesday = 55 minutes
Thursday = 25 minutes
Friday = x minutes

Average = (Monday + Tuesday + Wednesday + Thursday + Friday) / 5

40 = (45 + 30 + 55 + 25 + x) / 5

40 × 5 = 155 + x

200 = 155 + x

200 - 155 = x

45 = x

x = 45 minutes

Bus A travels according to the function y = 125/5x where y is distance traveled in miles and x is time in hours. Bus B travels a

Yuki888 [10]

Answer:

Bus B travel faster

Step-by-step explanation:

The graph of the question in the attached figure

we know that

the linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

x ---> is the time in hours

y ---> is the distance in miles

In this problem we have

Bus A

$y=\frac{125}{5}x$

The slope of the linear equation represent the speed of the bus

The speed of bus A is

$\frac{125}{5}=25\ miles/hour$

Bus B

Find the slope

take two points from the graph

(0,0) and (3,200)

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute

$m=\frac{200-0}{3-0}$

$m=66.67\ \frac{miles}{hour}$

Compare the slope Bus A with the slope Bus B

$66.67\ \frac{miles}{hour} > 25\ \frac{miles}{hour}$

therefore

Bus B travel faster
