two trains start from the station A and B travel towards each other at the speed of 16 miles/hour and 21 miles/hour respectively . at the time of the meeting the second train has travelled 60 miles more than the first . what is the difference between A and B ( in miles )
Step-by-step explanation:
Let the trains meet after t hours
Then, 21t – 16t = 60
⇒ 5t = 60 ⇒ t = 12 hours
∴ Distance between A and B
= (16 + 21) × 12
= 37 × 12 = 444 miles
