Can somebody tell me the answer to my question pls I need to know what the dependant variable is

Hey Hey here you go!

according to the chart thing y is the plane and x is hours

Question A-  so the plane(y) goes 600 miles x hours. it says 600 per hour so 600 miles an hour.

Question B- the dependant vriable is 6 from 600. why? because it was the main source for the eqauation and we used it to subract 300 from to get the next answer.

Question C- 600 miles x 600 miles is 1,200 miles. wich would be 1,200 miles for two hours. it said two and a HALF hour so half of 600 is 300 so add that to 1,200 + 300 is 1,500 miles in 2.5 hours (two and a half hours.)

Step-by-step explanation:

I hope this helped!!  Have a great dayyy
