Question : 117
Total: 200
Two trains, 330 and 110 m long, are going in the same direction. The faster train takes one minute to pass the other completely. If they are moving in opposite directions, they pass each other completely in 3 s. What is the speed of the faster train?
42 m/s
38 m/s
46 m/s
50 m/s
Validate
Solution:
(a ) Let the speed of faster train be x m/s and speed of slower train be y m/s.
According to the question,
240
x
−
y
= 60
⇒ x - y = 4 ......(i)
and
240
x
+
y
= 3s
⇒ x + y = 4 ......(ii)
On solving Eq. (i) and Eqs. (ii), we get
x = 42 m/s and y = 38 m/s
∴ Speed of faster train = 42 m/s
