A skateboarder rides by my office every 8 minutes, and a cyclist rides by every 10 minutes. How long will it take for the skateboarder and cyclist to ride by at the same time?

40 minutes

Step-by-step explanation:

10 times 4 = 40

8 times 5 = 40

so they will cross paths after 40 minutes of riding

none.

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
