Acceleration (II)

Time Limit: 1 sec

 

The Problem

We already know about Acceleration. The race is still going on. Now, we know the Velocity of the car increases uniformly from X ms-1 and after T s it becomes Y ms-1. Now he wanted to find the Acceleration and Distance of the car.

 

 

The Input

The input file contains 3 numbers X, Y (-100 <=X, Y <=100) and T (0 <= T <= 200).

 

The Output

For each line of input output will show two values rounded to 1 decimal places for both Acceleration and Distance in two separated lines.

 

Sample Input

18.5  46.1  2.47

 

Sample Output

11.2

79.8
