What is the distance?
1 Answer
"the distance covered by Claire prior to 10a.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"
Explanation:
Look at the graph when hours after 10.a.m equals to 0.
For Claire, she has travelled a total distance of 120 miles already while for Elena, she has not travelled at all. SO prior to 10.a.m, Claire has travelled 120 miles more than Elena
Look at the graph when Claire and Elena have finished travelling
Notice that Claire finishes 6 hours after 10.a.m which is 4.p.m
For Elena, she finishes 8 hours after 10.a.m which is 6.p.m
Therefore, Elena is on the road 2 more hours than Claire. Just to point out, both Claire and Elena have travelled a total of 360km but for Claire, she also travelled an extra 120km to get to Elena's place.
