x m/min for slower
x+3 m/minfor faster
30 minutes for 450 meters is 15 meters/min
combined speed is 2x+3 m/min
2x+3=15
2x=12
x=6 m/min for Delia
x+3=9 m/min for Becky

Let = the speed of the slower bike in m/min
= the speed of the faster bike in m/min
-----------------------
Since their speed will add, you can view this as
one of them moving at the sum of their speeds
and the other one standing still, so I can say:
m/min
and
m/min
------------------------------
Their speeds are 6 m/min and 9 m/min
---------------------------------------------
check:
and
and
m
OK
