Question

if the distance between two stations is 425 km, Two trains start simultaneously on parallel tracks to cross each other, one of them is greater than the other by 5km/hr. if the distance between the two trains after 3 hrs from the start is 20km, find the speed of each train.

Answer 1

Answer:

Hey mate your answer is here

Step-by-step explanation:

Given that distance between two stations= 425 km

Let the speed of the first train be x km/hr

Then the speed of other train is (x+5) km/hr

Distance travelled by first train in 3 hours = 3 × x km/hr = 3x km 

Distance travelled by second train in 3 hours = 3× (x+5) km/hr = 3x +15 km

Also given that distance between the trains after three hours= 20

By given data 

3x + 20 + 3x+15 = 425

6x + 35 = 425

6x = 425 - 35 = 390

x = 390 / 6 = 65 km/hr 

Therefore speed of first train = x = 65 km/hr

speed of second train = x + 5 = 65 + 5 = 70 km/hr
