Walking at 8KMPH From Point Q to Point railway station, mike will miss the train by 5 minutes. If he walks at 10KMPH he will reach the station by 5 minutes early.What is the distance between Point Q to Railway station?
Choose the most appropriate option.
A) A)9KM	B) B)6.66KM	C) C)7.25KM	D) D)12.40KM	E) E)13KM
Since time differences given are in minutes so let's convert speed in Km per minute   8 kmph = 8/60 km per minute = (2/15) km per minute   10 kmph = 10/60 km per minute = (1/6) km per minute   Let, Time of train to depart from station = t minutes   Distance between Point Q and Railway Station = Speed*Time = (2/15)*(t+5)   Distance between Point Q and Railway Station = Speed*Time = (1/6)*(t-5)   i.e. (2/15)*(t+5) = (1/6)*(t-5)   i.e. 12t+60 = 15t - 75   i.e. 3t = 135   i.e. t = 45 minutes   i.e. Distance = (1/6)*(t-5) = (1/6)*(45-5) = 40/6 = 20/3 Km = 6.66 Km   Answer: Option 6.66KM
