There is one railway on the island of Monday, which runs from Tuesday to Wednesday. There are two intermediate stops at Thursday and Friday. The trains run continuously from one end to the other at a constant speed, stopping for three minutes at each station. From departing Tuesday to arriving at Wednesday takes 42 minutes. From Tuesday to Friday takes 24 minutes. From Thursday to Wednesday takes 36 minutes. How long does it take from Thursday to Friday?

In going from Chicago to Atlanta, a car averages 45 miles per hour, and in going from Atlanta to Miami, it averages 55 miles per hour. If Atlanta is halfway between Chicago and Miami, what is the average speed from Chicago to Miami? Discuss an intuitive solution. Write a paragraph defending your intuitive solution. Then solve the problem algebraically. Is your intuitive solution the same as the algebraic one? If not, find the flaw.

Akira is running around a circular track. Akira runs counterclockwise. From where he starts, it takes him 22 seconds to reach the easternmost point of the track. It takes him 95 seconds to run one complete lap.Bob starts running at the same time as Akira. Bob starts from the northernmost point and runs clockwise. Bob and Akira pass each other for the first time after 26 seconds. How long does Bob take to run one lap of the track? The answer to this question should be the amount of time in seconds rounded to four decimal places that it takes for Bob to run a complete lap around the circular track.

An airplane flying into a headwind travels the 1500-mile flying distance between two cities in 3 hours. On the return flight, the airplane travels this distance in 2 hours and 30 minutesFind the airspeed of the plane (in mi/g) and the speed of the wind (in mi/h), assuming that both remain constant.
