Students usually go to school 5 days each week. many schools divide the school year into 4 9-week periods. how many days do students go to school during one 9-week period?

first one

Step-by-step explanation:

honestly I'm confused between the second and third option

but keep in mind that independent = x, dependent =y

so when the distance changes, it will affect the time.

but when the time changes, the speed will stay constant and under his control.

but if he said velocity it would be yes, when the time changes, it will affect the velocity because velocity is distance and time together as it differs from speed.

I hope you get it
