Question

'x'km are covered in 'y' hours. if x/2 km is covered in 4y hours, find ratio of old to new speed.​

Answer 1

Step-by-step explanation:

Let the length of the second train be x

Speed of both the trains = (40 - 22) * 5/18 = 5 m/s

Thus, (125 + x)/5 = 60 sec

or, 125 + x = 300

or, x = 175 m
