Question 295624:
A______60_______C____40____B
Alphonse starts at point A and runs at a constant rate toward point C. At the same time, Brigitte starts at point B and runs toward point C also at a constant rate. They arrive at C at exactly the same moment. If they continue running in the
same directions, Alphonse arrives at B exactly 10 seconds before Brigitte arrives at A. How fast was Brigitte running?

r*t=d
I am assuming that the 60 and 40 are distances.
t=d/r
60/a=40/b
60/b=40/a+10
a=5 b=10/3 =3 1/3 units per second
We don't know what units are being used.
