-
- Let the speeds of the two trains be x m/sec and y m/sec respectively.
Then, length of the first train = 27x metres,
and length of the second train = 17y metres.
27x + 17y / x+ y = 23
27x + 17y = 23x + 23y
4x = 6y
x/y = 3/2

- Let the speeds of the two trains be x m/sec and y m/sec respectively.
Then, length of the first train = 27x m,
and length of the second train = 17y m
(27x + 17y) / (x+y) = 23
27x + 17y = 23x + 23y
4x = 6y
x/y=6/4=3/2 - 9 years agoHelpfull: Yes(6) No(0)
