Question

Two trains each 61 m long are moving towards
each other on parallel lines with velocities of 32 and
48 km/hour respectively. Find the time that elapses
from the instant when they first meet until they
have cleared each other.
(1) 4.34 s
(2) 3.28 s
(3) 6.45 s
(4) 5.45 s​

Answer 1

Answer:

the answer is 4. i.e 5.45 sec

Explanation:

the velocities will be added as they are opposite to eachother and the distance will be doubled so 122/ 22.22 = 5.49 because we need to change the unit of velocity in MTR/ sec.

Answer 2
