Simon wants to drive 450 miles in 12 hours. He knows that stopping for breaks will take a total of 3 hours. What

should be his average speed in miles per hour?

45

30

50

38

I believe it would be 50

Step-by-step explanation:

If those 3 hours are included in those 12 to get there, then you'd want to subtract that to get your actual time spent driving. That would leave you with 9. Then, you'd divide that by 450 to get your answer. (This is if those 3 hours are included in that 12 hour time frame.)
