There are two processes P1 and P2.

P1's total processing time is 70 ms.

P2's total processing time is 60 ms.

Context switch time between processes = 20 ms.

Context switch time between threads of same process = 0

Timer interrupt time = 40 ms

Process 1 goes for I/O request after 40 ms of its execution, and this I/O takes 40 ms to complete.

Process 2 spawns a new thread T2 after 40 ms of its execution. This new thread T2's total processing time is 40 ms.

Write a timeline starting from 0 ms until completion of all processes and threads.
