Question

if I walk at 3 kilometre per hour I miss the train 2 minut if however I walk 4 kilometre per hour I reach the station 2 minute before the arrival of the train how far do I work to reach the station ​

Answer 1

Answer:

Distance = 800 metres

Step-by-step explanation:

Let's assume the distance between your work place and the station is d kilometre

Time required @3 kilometre per hour is $\frac{d}{3} hours$

Time required @4 kilometre per hour is $\frac{d}{4} hours$

According to the problem:

$\frac{d}{3} - \frac{d}{4} = \frac{2}{60} - \frac{-2}{60}$  [converting min into hrs,

                           2 min before is positive and 2 min late is negative]

$d = \frac{12}{15} kilometres = \frac{4}{5} kilometres = 800 metres$
