Answer:
16 hours
Step-by-step explanation:
So first you need to find out how far away the store is from the warehouse. You can do that by adding the 2 x-coordinates together because they are positive and negative. That gets you 40, then you multiply 40*20 because each grid unit represents 20 miles, and you get 800 miles. Finally, you divide 800/50 to see how many hours it takes, and you get 16 hours. I hope this helps.
