Answer:
Slower train is at 40km/hr
Fastest train is at 50km/hr
Step-by-step explanation:
The distance between the stations is 250km and after 2.5 hours the trains are 25km apart.
The total distance that the trains have traveled is 250km - 25km or 225km.
Let X be the speed of the slower train in km/hr
225km = 2.5X + 2.5{X+10}
Simplify the equation
225 = 2.5X + 2.5X + 25
Combine like terms
225 = 5X + 25
Subtract 25 from both sides
200 = 5X
Divide both sides by 5
40 = X
The slower train is moving at 40km/hr.
That means that the faster train is moving at 50km/hr
