Answer:
The answer to your question is 450 km
Step-by-step explanation:
Data
First stage                      Second stage
speed 1 = 40 km/h         speed 2 = 65 km/h                      
time 1 = 8 h                     time 2 = 2 h
Process
1.- Write the formula to calculate the speed
     speed = distance / time
-Solve for distance
     distance = speed x time
2.- Calculate the distance of the first stage
     distance 1 = 40 x 8
     distance 1 = 320 km
3.- Calculate the distance of the second stage
     distance 2 = 65 x 2
     distance 2 = 130 km
4.- Calculate the total distance 
     Total distance = 320 + 130
                              = 450 km
 
        
                    
             
        
        
        
Answer:
C
Step-by-step explanation:
For lines l and m and the transversal line that creates angles 6 and 18, angles 6 and 18 are corresponding angles of lines l and m. If they are congruent, lines l and m are parallel.

Answer:
Slope = 
Step-by-step explanation:
We can define the slope as the "change in y values" divided by the "change in x values".
By change in, we mean, 2nd point MINUS the first point values.
The points given is:
(1,4)  &  (-1,-1)
<u>Change in y value:</u>
-1 - 4 = -5
<u>Change in x value:</u>
 -1 -1 = -2
Slope is -5/-2 = 5/2
There is no answer choice. The correct answer is 5/2
