2000m

Let in time t ,I reach the bus stand with a speed v m/min. and distance between home and bus stand is x meter(m).

4 km/hr = 4*1000/60 = 200/3 m/min

5 km/hr = 250/3 m/min

t = x/(200/3) - 3

t = x/(250/3) + 3

x/(200/3) - 3 = x/(250/3) + 3

x = 2000m

time = 2000/(200/3) - 3 = 27min.

speed = 2000/27 m/min

hence distance between bus stand and home = 2000m

Answer 2

Let in time t ,I reach the bus stand with a speed v m/min. and distance between home and bus stand is x meter(m).

4 km/hr = 4*1000/60 = 200/3 m/min

5 km/hr = 250/3 m/min

t = x/(200/3) - 3

t = x/(250/3) + 3

x/(200/3) - 3 = x/(250/3) + 3

x = 2000m

time = 2000/(200/3) - 3 = 27min.

speed = 2000/27 m/min

Hence distance between bus stand and home = 2000m
