laughing is the best medicine

 Two friends who were weak in mathematics were sitting ready for an interview.

  When the first number came, he entered...

 Officer: What will you do if you are traveling by train and you suddenly feel hot?

 Candidate: I will open the window.

 Officer: Very well, now tell me if the window is 1.5 square meters and the area of ​​the box is 12x90 feet and the train is moving south at 80 km/h and the wind is blowing from the south at 5 miles per second in the box.  How long will it take for the entire box to cool down when entering?

 The candidate tried but could not answer and failed.

 Coming out, he told that question to his friend

 Now it was his turn.

 Officer: You are traveling in a train, what will you do if you suddenly feel hot?

 Candidate: I will take off my coat.

 Officer: What will you do if you feel hot?

 Candidate: I will take off my shirt.😜😂

 Officer: (sigh) What will you do if you still feel hot?

 Candidate: I will take off my vest.😂

 Officer: (angry 😣😤) If it still gets hot?

 Candidate: I will also take off my pants. 😂😂😂😂

 Officer: (very angry) If it still gets hot?

 Candidate
