Trains Boats and Streams Practice Test 2 with solutions

Let the length of the platform = x m
Length of the train = 320 meters
Speed of the train = 120 kmph
Time = 24 seconds
So,

24

60×60

=

x+320 1000

120

24×120

3600

=

x+320

1000

4

5

=

x+320

1000

4,000 = 5x + 1,600
5x = 2,400
x = 480 meters
Man crosses the same platform in 4 minutes = 4 × 60
= 240 seconds
Speed of the man =
