D=R%2At
For Sue,
D%5BS%5D=30%2At
For Jane,
D%5BJ%5D=20%2A%28t-3%29
where t is measured from when Sue left.
D=D%5BS%5D%2BD%5BJ%5D
30t%2B20%28t-3%29=490
30t%2B20t-60=490
50t=550
t=11hr
So then Sue traveled 11 hours and covered 330 miles and Jane traveled 3 hours less or 8 hours and covered 160 miles.
