Question

I walk at the rate of 4 km per hour I miss the train by 10 minutes if I walk at the rate of 5 km per hour I reach 5 minutes before the arrival of the train how far is the station from my house assuming that I start working from my house

Answer 1

Answer:

5 km

Step-by-step explanation:

Let, station be distance D km from your house

and let train arrives in time T minutes

equating the distance

D => 5*(T-5) = 4*(10+T)

 => 5T - 25 = 40 + 4T

 => T = 25 +40 = 65 minutes

 => D = (5/60)*(65 - 5) = 5 km

(please note, speed is divided by 60 to convert it into km/min)
