It travels at this speed for 2 hours to reach at itsdestination. If the fault had occurred 50 miles later on, the train would have reachedits destination 45 minutes early. Find the distance traveled by the train. Let the actual speed of train be X miles/hour. after fault its speed will be reduced to 3X/5 miles/hour. If we could find the speed of the train, we will get the solution!!!by seeing one can find that A farmer has C chickens. A sack of feed comes for 9 days. As the feedcost is increasing the farmer sells some chickens and retains 12 chicken. If he reduces thefeed quantity by 10% .Then he observes that the feed comes for 30 days. What is C? C chickens can b fed for 9 days. So C chick can eat 1/9 in 1 day.So 1 chick can eat (1/9C) in one day. After his reduction one chick gets to eat only 90% of what it used to eat in one day.So new feed value=0.9*(1/9C) Vacation timeIt was vacation time, and so I decided to visit my cousin's home.
