Answer by TimothyLamb(4379)   (Show Source):
You can put this solution on YOUR website! x = maria speed
y = carlos speed
---
x = y + 5
---
s = d/t
t = d/s
---
maria time:
t = 7/x
t = 7/(y + 5)
---
carlos time:
t = 6/y
---
equate times:
7/(y + 5) = 6/y
7y = 6(y + 5)
7y = 6y + 30
y = 30
x = 35
---
answer:
x = maria speed = 35 kph
y = carlos speed = 30 kph
