7 Joe took 138 seconds to swim 150 m.
He was 30 seconds faster than Don
How long did Don take in minutes and seconds?
1387 30 , 168​

168

Step-by-step explanation:

If he was faster than Don then it should've taken him less time. So Don would've taken 30 seconds MORE

138+30=168

Don Took 2 Mins. And 48 Seconds.

How I Found The

138 + 30 = 168 Seconds

168 Seconds Is Equal To 2 Mins. And 48 Seconds.

So Don Took 2 Mins. And 48 Seconds To Swim 150 M

ou would have 12 of each

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'.
