A submarine starts at sea level and descends at a rate of 20 meters per minute for 2 hours.Which statement describes the submarine's descent?

Answer 1

A)The submarine descends to a level of 3,600 meters after 1 hour.
B) The speed of the submarine's decent is 900 meters per hour.
C)After 2 hours, the submarine has descended -3,600 meters.
D)The submarine descends to a depth of -3,600 meters.

Answer 2

At 20 meters per minute, the sub would be descending at 60 * 20 = 1200 meters per hour

Answer 3

Thank you!

Answer 4

You're welcome -- but my answer doesn't match any of your answers.

Answer 5

I see 3600 m mentioned in 3 of your choices. Agreeing with Ms. Sue that the answer does not match any of your choices, I suspect a typo and your rate of descent is 30 m/min.

Answer 6

Thank you,I was thinking the same thing when I received this question for my homework.
