I started on my bicycle at 7 a.m. to reach a certain place . After going a certain distance, my bicycle went out of order. Consequently, I rested for 35 minutes and came back to my house walking all the way. I reached my home at 1 p.m. If my cycling speed is 10 kmph and my walking speed is 1 kmph then on my bicycle I covered a distance of 4(61)/(66)k m b. 13 4/9k m c. 14 3/8k m d. 1(10)/(21)k m
