Answer by TimothyLamb(4379)   (Show Source):
You can put this solution on YOUR website! x = alice speed
y = gloria speed
x = 4y
---
s = d/t
---
their relative speed:
x + y = 280/8
x + y = 35
4y + y = 35
5y = 35
y = 7
x = 4y
x = 4*7
x = 28
---
answer:
x = alice speed = 28 mph
y = gloria speed = 7 mph
