Let's give some distances
100 up 100 flat 100 down meters
then return 100 up 100 flat 100 down


time required (distance/rate = time ) 200/100 + 200/120 + 200 / 150 = 5 hr

distance 600


distance / time = average speed = 600/5 = 120 m/s

Answer:

Option B

Step-by-step explanation:

Slope of the line is calculated by the formula:

m=\frac{y_2-y_1}{x_2-x_1}\\\\

We have the points ( -2 , 4) and (3 , -5) so plug in the values in the formula:

m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{-5-4}{3-(-2)}\\\\m=\frac{-9}{5}\\

so the slope(m) equals -9/5

Find The value of x, y and z​
Ratling [72]

Answer:

x = 18 ; y = 10 ; z = 102°

Step-by-step explanation:

The triangle in the pic is an isosceles triangle.

As it is an isosceles triangle , it's two sides will be equal .

=  > 3x - 42 = 12

=  > 3x = 42 + 12 = 54

=  > x = \frac{54}{3}  = 18

Also, both the base angles will be equal.

4y - 1 = 39

=  > 4y = 39 + 1 = 40

=  > y =  \frac{40}{4}  = 10

According to angle sum property of a triangle , sum of measure of all the angles of a triangle is equal to 180°. So,

z + 39 + 39 = 180

=  > z + 78 = 180

=  > z = 180 - 78 = 102
