Write a program that calculates the speed of a vehicle using the formula:

\[\text{Speed} = \frac{\text{Distance}}{\text{Time}}\]

Round the result to 2 decimal places.

Input

The program should prompt for:

  1. Enter the distance in metres:
  2. Enter the time in seconds:

Both values are entered as decimals (floats).

Output

The speed is speed m/s

Example

Input:

100.0
9.58

Output:

The speed is 10.44 m/s
