A goods train starts from station A to the station B and at the same t

1.	A goods train starts from station A to the station B and at the same time a passenger train starts from station B to station A. After meeting they reached their destination in 9 hours and4 hours respectively. Find the ratio of their speed.
Answer» ANSWER: 680 Step-by-step explanation: ANSWER Solution: Given Train starts at the same time. Hence, Time REMAINS constant. Speed of Train 'T1' be 'S1' = 40 km\hr Speed of Train 'T2' be 'S2' = 45 km\hr Let X be the distance at which trains meet. Train T2 travels X+40 km more than Train T1 According to the formula. Speed= Time Distance Time= 45 X+40 Time= 40 X From above two equations. 40 X = 45 X+40 45×X=40×X+40×40 5×X=1600 =320 km Distance between two Stations = Distance at which train T1 meet + Distance at which Train T2 meet + Distance train T2 travels = 320+320+40 = 680

680

Step-by-step explanation:

ANSWER

Solution:

Given Train starts at the same time.

Hence, Time REMAINS constant.

Speed of Train 'T1' be 'S1' = 40 km\hr

Speed of Train 'T2' be 'S2' = 45 km\hr

Let X be the distance at which trains meet.

Train T2 travels X+40 km more than Train T1

According to the formula.

Speed=

Time

Distance

Time=

X+40

Time=

From above two equations.

X+40

45×X=40×X+40×40

5×X=1600

=320 km

Distance between two Stations = Distance at which train T1 meet + Distance at which Train T2 meet + Distance train T2 travels

= 320+320+40

= 680
