in min hr she goes km so rest km she goes with km/h speed, time taken in full journey












now we know that the distance is km

3rd condition ::
again given ,if she used km/hr for minutes and then redued speed to then she reached here minutes late (this condition is wrong)
in mins she goes km = km

remaining distance = v - (3v)/4 = v/4

total journey is for min ( as we found t = 1 hr)
but she is late by mins
so now her total journey is for mins

for this v/4 km she takes 45 mins => her speed is 60 xx v/4 xx 1/45 = v/3 km/h (2v)/5 km
