Which of the following would be the best example of parallel lines in the real world a; a bridge extending over a river b; a four way stop at an intersection c ; the northbound and southbound on a straight highway d; the lines formed on a windowpane

Real life example of parallel lines are railroad tracks and rows in a garden. Also the lines on a basketball court are parallel so basically C if im positive

Step-by-step explanation:

Some examples include the structural frames of buildings, railroad tracks, windows (opposite sides), sailboats, steps, and paper.

parallel bars in men's gymnastics

Also anything that is shaped as a rhombus, square or a rectangle. ( added by a.m.b.)

Answer with explanation:

 Two lines are said to be parallel ,if you take infinite number of points on any of the line and draw Perpendicular to another line , the length of Perpendiculars will be same.

Now coming to Options

A:--When you look at the bridge which extends over a river ,it is not exactly parallel ,the two opposite sides that is Line segments ,of the bridge are not exactly parallel.You may call it Skew lines.

B:--Similarly, a four way stop at an intersection , are not exactly Parallel.

C:--The straight Highway ,is not entirely Parallel at each and every part of the two lines joining on the Highway.So, you can't say that northbound and southbound on a straight highway are parallel everywhere.

D:--The Lines formed on the windowpane are smaller segments.These Segments are Parallel.

⇒Option D , is most Appropriate ,that is the best example of parallel lines in the real world.

step-by-step explanation:

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
