Answer: No
Explanation:
The diver is at 60m below sea level, and swims upward 2m every 5 seconds.
So, since there are 24 five-second periods in 2 minutes (60secs/min), the diver would have swam up 48m after 2 minutes.
Since 60m - 48m is 12m, the diver has not yet reached the sea surface.
Hope it helps :)
