Question 186747
Let the speed of A train = v mph then speed of E train = v+12 mph
speed = distance/time so time = distance/speed

Applying the given conditions 230/v = 290/(v+12)
Cross multiplying we get
230v + 12(230) = 290v
(290- 230)v = 12(230)
60 v =12(230)
v = 46 mph 
So the A train is 46 mph and E Train is  58 mph  (46+12 = 58)
