11. The distance between two stations is 250km. Two trains started simultaneously for both
the stations in opposite directions. The distance between them after 2 1/2 hours is 25 km if the
speed of one train is 10km/hour more than the other. Find the speed of each train​

Answer 1

Answer:

Use the formula of speed= distance/time

Answer 2

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
