Question 26330: I have been racking my brain for hours over this one, and I can't seem to find any info on the internet about it.
Train A leaves the station at 1pm heading north at 65 mph. Train B leaves the same station 1 hour later traveling south at 55 mph. How long will it take the trains to be 365 miles apart?
Please help.
Thanks!

TRAIN a TIMES x+1
TRAIN b TIMES x
together they = 365
65(x+1)+55(x)=365
65x+55x+65=365
120x=300
x=2.5

Hence, it will take train a 3.5h and it will take train b 2.5h to be 365 miles apart.
Paul.
