Answer 2

Given:-

• A train 120m long passes a railway platform.
• Length of train (Distance) = 160m.
• Time taken by the train (t) = 8 sec.

To find:-

• Find how long will it take to pass another platform 100m long.?

Solutions:-

We have given that;

• Distance = 160 + 120 = 280
• Time taken = 8 sec

According to the questions;

Speed => Distance/Time

Speed => 280/8

Speed => 35m/s

• New Distance = 100m
• Speed = 35m/s

Time => Distance/Speed

Time => 100/35

Time => 2.85sec

Hence, the train covered the 100m distance is 2.85 second.

Some Important:-

• Distance => Speed/Time
• Speed => Distance/Time
• Time => Distance/Speed

Units:-

• Time = sec, min, hours
• Distance = meter, kilometre
• Speed = km/hr, min/sec
