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?
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.
At 20 meters per minute, the sub would be descending at 60 * 20 = 1200 meters per hour
Thank you!
You're welcome -- but my answer doesn't match any of your answers.
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.
Thank you,I was thinking the same thing when I received this question for my homework.
To describe the submarine's descent, we need to determine the change in its position from sea level. Given that the submarine descends at a rate of 20 meters per minute for 2 hours, we can calculate the total descent.
First, convert the time from hours to minutes. Since there are 60 minutes in an hour, multiply 2 hours by 60 minutes per hour:
2 hours * 60 minutes/hour = 120 minutes
Next, calculate the total descent by multiplying the descent rate of 20 meters per minute by the total time of 120 minutes:
20 meters/minute * 120 minutes = 2400 meters
Therefore, the submarine descends by 2400 meters from sea level during the 2-hour period.
