Stations A and B are 587 km apart. One train starts from A to B and at the same time
another train which is 18 km/h faster starts from B to A along a parallel track. If after 3 and a half hour the distance between both the trains is 34 km, find the speed of each of the trains.
Answers
Acc. To me,
Answer is 70 km/h and 88 km/h
------------------------------------------------------------
Suppose train A at A and train B at B
A----------------------------------B
|--------587Km------------------|
-----> <------
v v+18
After (3and 1/2 hr) or 7/2 hr
A--------------°-------------------°---------------------B
∧|-----34km---|∧
| |
trainA trainB
|---X-----------||-----34---------||----[587-x-34]---|
-X is distance travelled by A after 7/2 hr
-587-x-34=553-x is distance travelled by B
Speed =Distance/time
For Train A
v=x/(7/2)---------1
For train B
v+18=553-x/(7/2)-----------2
put x from 1 to 2
v=70 km/h----First train speed
v+18=88 km/h---2nd train speed
Sorry for bad drawing
I hope it help
Answer:
hi mate
A train speed =70km/h
B train speed =88km/h
hope it will help you
