speed of Sarita = 2.5 kph
speed of Julie = 2kph
relative velocity= speed of Sarita + speed of Julie= 2.5+2=4 kph
distance covered = 18 km
time= distance /speed= 18/4=4.5 hr
speed of Julie = 2kph
relative velocity= speed of Sarita + speed of Julie= 2.5+2=4 kph
distance covered = 18 km
time= distance /speed= 18/4=4.5 hr
