Answer 2

Answer:

220mins

Step-by-step explanation:

First We have to convert all the Values to seconds

So, 3min 20sec ={(3x60)+20}sec = 200sec

3mins 40sec=220sec

4mins=4x60sec = 240sec

Now, find the LCM of 200sec, 220sec, 240sec = 1320 sec

Now, Convert it in the form of mins = 1320/60 mins = 220mins
