A snake slides through a long cylindrical hole in the ground at 5 centimeters per second. The hole is 7.3 meters in length. The snake takes 14 seconds to enter the hole.
What is the length in centimeters of the snake ?

Answer 1

The snake has entered the hole when its tail just comes into the hole. It is given that 14 seconds elapse from the time the snake's head enters the hole till its tail enters. Thus,

Length of the snake = Distance traveled in 14 seconds
= (5 cm/s) × (14 s) = 70 centimeters.

Answer 2

Answer is 70 centimeters.
