To travel a distance of 600 km, the slower train takes 4 hrs
more than the faster one. However, if the speed of the
slower is doubled, it takes 1 hrs less than the faster train.
Find the speed of the faster train.

Answer:
my dear this is physics anyway i will answer you question
Explanation:
Let consider Express train time=t1
Duronto train time =t2
For first case t1 = t2 + 3 hour
For second case 2*t1 = t2 - 4.5 hour
Velocity=distance/time
Take V1=velocity of express train
《1》V1=600 km / t2+3 hour
《2》2*V1=600km / t2-4.5 hour
《2》÷《1》
t2=12 hour
Now, consider V2= velocity of Duronto train
V2=600km / 12 hour
velocity of Duronto train= 50 Km/hour.
Answer:
The correct answer of this question is 12 hour.
Explanation:
Given - A distance of 600 km, the slower train takes 4 hrs more than the faster one.
To Find - Find the speed of the faster train.
According to the question,
In the first case - t1 = t2 + 3 hour
In the second case 2 × t1 = t2 - 4.5 hour
Use the ,
Velocity=distance/time
Take V1 = velocity of express train
V1 = 600 km / t2 + 3 hour ....1)
2 × V1 = 600km / t2 - 4.5 hour ....2)
From equation 2 - equation 1
t2 = 12 hour
V2 = 600km / 12 hour
