A woman begins bicycling with a pace of 8 kmph and she increases her pace every two hours by 2 kmph. She does not increase her pace as soon as her pace reaches her maximum speed of 12 kmph. How many hours did she bicycle if she traveled 64 kms?  Choose the correct choice from the following options.
A) 6 1â„7 hours B) 6 2â„7 hours C) 8 2â„7 hours D) Cannot be determined E) None of these
Distance covered in first two hours = 8 Ã— 2 = 16 km   Distance covered in next two hours = 10 Ã— 2 = 20 km   Distance covered in next two hours = 12 Ã— 2 = 24 km   Distance covered in first six hours     16 + 20 + 24=

60 km   Remaining distance= 64 â€“ 60 = 4 km.   Now, this distance will be covered at the speed of 12 km/hr.   âˆ´ Time taken = 4â„12 = 1â„3 hour.   Total time= 6 + 1â„3 = 6 1â„3 hour   Answer None of these
