A train leaves the station at 9:00 pm traveling east at 36 miles per hour a second train leaves the station at 10:00 pm traveling west at 42 miles per hour at what time will both trains have traveled the same distance
Add the time they arrive at the common to individual starting points. 9.00 +[tex] \frac{x}{36} =10.00 + \frac{x}{42} [/tex] put the like terms together; 10.00 - 9.00=[tex] \frac{x}{36} - \frac{x}{42} [/tex] 1=[tex] \frac{42x-36x}{36*42} [/tex] 1=[tex] \frac{6x}{36*42} [/tex] 6x=36*42 x=[tex] \frac{36*42}{6} [/tex] x=252 miles
