Question 80830: Two vagabonds who are 200 miles apart travel towards each other. If they start at 2 p.m. and meet at 6 p.m., and one vagabond is traveling 10 miles per hour faster than the other, what are the speeds of both vagabonds?
I tried using rate x time = distance like our teacher said, and this is what i got::
((Vagabond A, Vagabond B))
..........(r)........(t)..=..d
A........x
B........x+10
total................4h.....200mi
Then i divided 200 by 4 and got 50, so I got 50 mph and 60 mph... am I right?
Thank You!
