Answer:
6 minutes and 29 seconds
Step-by-step explanation:
Subtract 30 from 59 to make it a bit easier, than add that 30 to 1 minute and 30 seconds and you would get 2 minutes exact. Then add the 4 minutes and you get 6. Also remember the extra 29 seconds and add that to the 6, and you get 6 minutes and 29 seconds.
