Nana76 [90]

we are given

Jimmy is trying to escape Jane

For finding total distance , we will find distances and then add them

He runs 12 km/hr for 5 minutes

First distance:

speed =12 kh/hr

time=5 minutes

we can change into hour

t=\frac{5}{60}hr

d_1=s*t

now, we can plug values

d_1=12*\frac{5}{60}

d_1=1

second distance:

speed =17 kh/hr

time=8 minutes

we can change into hour

t=\frac{8}{60}hr

d_2=s*t

now, we can plug values

d_2=17*\frac{8}{60}

d_2=2.26667

third distance:

speed =6 kh/hr

time=2 minutes

we can change into hour

t=\frac{2}{60}hr

d_2=s*t

now, we can plug values

d_3=6*\frac{2}{60}

d_3=0.2

now, we can find total distance

d=d_1+d_2+d_3

d=1+2.26667+0.2

d=3.46667

so,

total distance is 3.46667 km...........Answer

Find the average rate of change of a function that contains the points (-2,3) and (2,5). -2, -1/2, 1/2, 2
UkoKoshka [18]

Answer:

The answer is "\frac{1}{2}".

Step-by-step explanation:

Given points:

(-2,3)\\\\(2,5)\\\\

average rate=?

x_1=-2\\\\y_1=3\\\\x_2=2\\\\y_2=5

average\ rate=\frac{y_2-y_1}{x_2-x_1}

                     =\frac{5-3}{2-(-2)}\\\\=\frac{5-3}{2+2}\\\\=\frac{2}{4}\\\\=\frac{1}{2}
