A couple went on for a climbing trip. But only the husband returned from the vacation and said that his wife slipped off while climbing and died. On investigating, the local sheriff arrested him saying, 'Your travel agent called. You murdered your wife.'
The man did not inform anyone about the trip. Then how did the agent was so sure that it is a murder?
Today is more windy than yesterday, will a return flight take the same time, less time, or the same amount of time to complete?
(The 'Google Riddles' are interview questions those who wish to get hired were asked).
Let's do a worked example. Lets say our plane has to travel 300 miles there and 300 miles back. It has a standard cruising speed of 600mph. In the case of no wind it will travel the 600 miles in 1 hour exactly. Simple enough. Let us say that the wind speed is 100mph so the plane will be wind assisted to 700mph and slowed to 500mph - Wind Assisted: 300 miles at 700mph takes 0.429 hours - Wind Slowed: 300 miles at 500mph takes 0.6 hours - Total Time: 1.029 hours
