Answer 2

Step-by-step explanation:

Solution (a) :- Change in position of the submarine in 1 minute = -10 m

So, the position of the submarine after half an hour = -10 × 30 = -300 m

Solution (b) :- Position of the submarine after 1 1/2 hours = -10 × 90 = -900 m

( Since 1 1/2 = 3/2 hours = 3/2 = 60 = 2 × 30 = 60 = 90 minutes )
