Ram travels 300 km to his home partly by train and partly by bus. He takes 4 hours if he travel 60km by train and the remaining by bus. he takes 10 minutes longer. find speed |
|
Answer» ong>Answer: Please Mark As Brainliest Step-by-step explanation: Roohi travels 300 km to her home partly by train and partly by bus. She takes 4 hours if she travels 60 km by train and the remaining by bus. If she travels 100 km by train and the remaining by bus, she takes 10 minutes longer. Find the speed of the train and the bus separately. Share Study later ANSWER LET the speed of the train be x km/hr and the speed of the bus is y km/hr. So according to QUESTION and USING Time= Speed Distance
Total distance =300 km Roohi travels 60 km by train and 300−60=240 by bus in 4 minute, x 60
+ y 240
=4 and 100 km by train, 300−100=200 by bus, and takes 10 minutes more, x 100
+ y 200
=4+ 60 10
⇒ x 100
+ y 200
= 6 25
Now, let x 1
=u and y 1
=v then 60u+240v=4.............eq1 100u+200v= 6 25
..............eq2 multiply eq1 by 5 and eq2 by 6 we get 300u+1200v=20..........eq3 600u+1200v=25...........eq4 Subtracting eq3 QND eq4 we get −300u=−5 u= 300 5
= 60 1
Putting the value of u in eq1 we get 60× 60 1
+240v=4 240v=3 v= 240 3
= 80 1
Now x 1
=u= 60 1
∴x=60 and y 1
=v= 80 1
∴y=80 Hence the speed of the train is 60 km/hr and the speed of the bus is 80 km/hr. |
