| Understanding | Application |
|
When 2 objects are moving in opposite directions their relative speed is = speed of train 1 + speed of train 2 Time = Distance/Speed |
At 10am Train A will cover 60kms. remaining distance(500-60 = 440) will be covered by speed of 60 + 40 = 100km/hr 440/100 = 22/5=4 hours 24 minutes so they will meet after 4 hrs 24 mins of 10 AM = 2.24 PM
