PLZ HELP ME!!!

Claire and Elena are going on a road trip with their families. They plan to meet at Elena's house and then follow each other. Claire meets Elena at her house at 10 a.m. Elena is held up by chores and has to leave late, but Claire continues on. The total distance traveled by Claire and Elena is represented on the graphs below.

Compare the two graphs and choose the correct answer.

A.
The distance covered by Claire prior to 10 a.m. was 120 miles more than the distance covered by Elena prior to 10 a.m. After leaving Elena's house, Claire was on the road two hours more than Elena.

B.
The distance covered by Claire prior to 10 a.m. was 60 miles more than the distance covered by Elena prior to 10 a.m. After leaving Elena's house, Elena was on the road one hour more than Claire.

C.
The distance covered by Claire prior to 10 a.m. was 60 miles more than the distance covered by Elena prior to 10 a.m. After leaving Elena's house, Claire was on the road one hour more than Elena.

D.
The distance covered by Claire prior to 10 a.m. was 120 miles more than the distance covered by Elena prior to 10 a.m. After leaving Elena's house, Elena was on the road two hours more than Claire.

The distance covered by Claire prior to 10 a.m. was 120 miles more than the distance covered by Elena prior to 10 a.m. After leaving Elena's house, Claire was on the road two hours more than Elena.

As we can see that Claire's graph opens at zero but Elena's graph opens at 2 hours, this proves, Claire was 2 hours ahead of Elena.

And at zero, Claire is at 120 miles, while Elena is zero, so this means her distance covered was more than Elena.
