Hi I need a little help with a couple math questions I believe I have the answers, if someone can please just check them thank you.

1. The table shows the number of miles driven over time.
Time 4|6|8|10
Miles 204|306|408|510

Express the relationship between distance and time in simplified form as a unit rate. Determine which statment correctly interprets this relationship.
A. 51/1; your car travels 51 miles every 1 hour
B. 204; your car travels 204 miles
C. 1/51 You car travels 51 miles every 1 hour.
D. 10; your car travels for 10 hours.

I believe the answer is A, although it could be C.
