Find Distance Between Two Places If Speed is
If walk at 5 km/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:
- 6 km
- 5 km
- 5 km
- 7 km
Answer: (1) 6 km
Explanation:-
Let be the distance is X km
According to the question,
X/5 + 7/60 = X/6 – 5/60
X/5 – X/6 = -5/60 – 7/60
X/30 = – 12/60
X/30 = – 1/5
X = – 30/5
X = -6 (Distance is always in positive)
The, X = 6 Km
Hence, the answer is (1) 6 km.
