Q: Arun and Bhaskar start from place P at 6:00 am and 7:30 am, respectively and run in the same direction. Arun and Bhaskar run at 8 km/h and 12 km/h. respectively. Bhaskar overtakes Arun at?

Distance between Arun and Bhaskar at 7:30 am = 8 x 11/2 = 12 km Time taken by Bhaskar in covering a distance of 12 km = 12/(12 - 8) = 3 h ∴ Required time = 10 : 30 am

10 : 30 am
9 : 00 am
11 : 30 am
1 : 00 am

Correct Answer: 10 : 30 am

Explanation:

Distance between Arun and Bhaskar at 7:30 am = 8 x 1¹/₂ = 12 km
Time taken by Bhaskar in covering a distance of 12 km = 12/(12 - 8) = 3 h
∴ Required time = 10 : 30 am
