If I walk at 5km/hr, I miss a train by 7 minutes. However, if I walk at 6 km/hr I reach the station 5 minutes before the departure of the train. The distance between my house and the station is
let the distance between b/w home and station is xkm
time= distance/speed
distance = time*speed
in both cases distance is same.
so,
t1-7/60 = t2+5/60
x/5 - 7/60 = x/6 + 5/60
x = 6km
answer is option D.
