IF YOU TRAVEL 82 km IN 40 MINS, WHAT IS YOUR SPEED IN km/h?

123km/h

Step-by-step explanation:

I really don't know the right way to explain it but the way I did it is just devide 82 by 2 so I can get the speed for 20 mins, then just multiply what I got for 20 mins by 3

82:2=41km/h

41x3=123km/h

hey why u asking same question again and again

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

me! what did you put for this question?
