<PRE><B>Question 927373</B>
relative speed of the two trains:
70 + 30 = 100 mph
---
time when the trains meet:
s = d/t
t = d/s
t = 300/100
t = 3 hours
---
distance traveled by the train that starts at point B, when the trains meet:
d = st
d = 70*3
d = 210 miles
---
answer:
(G) 210 mi
