Question 735157
Determine the average speed of each brother.
Two brothers drive toward each other on I-95.
 One starts in Kittery and the other in Houlton; which are 325 miles apart.
 they meet after 2 1/2 hours. One brother averages 10 mph faster then the other. 
:
That's close, it should be:
2.5s + 2.5(s+10) = 325
2.5s + 2.5s + 25 
5s + 25 = 325
s = 300/5 = 60
