Calculate Total Time for Journey

Four friends are on a journey where each friend walks from the starting point to a destination and then returns. In addition, each friend experiences a fixed extra delay due to crowd navigation. The total time spent by a friend is given by the formula:

where:

• (d) is the distance from the starting point to the destination,
• (s) is the walking speed, and
• (t) is the additional delay time.

Your task is to compute and print the total time for each friend. Each friend’s data is provided on a new line in the input.

inputFormat

The input consists of four lines. Each line contains three space-separated integers representing the distance (d), the speed (s), and the additional delay time (t) for a friend.

outputFormat

Output the total time for each friend on a separate line. The total time is calculated as (\frac{2d}{s} + t) and should be printed as an integer.## sample
