Question

A submarine is submerged at a depth of -150 meters. The submarine ascends at a rate of 8 meters per minute. How many minutes will it take for the submarine to reach a depth of -46 meters?

Answer 1

The submarine will take 13 minutes to ascend from -150 meters to -46 meters by ascending at a rate of 8 meters per minute.

Step-by-step explanation:

To calculate the number of minutes it will take for the submarine to ascend from a depth of -150 meters to -46 meters, we can use the following steps:

1. First, find the total distance the submarine needs to ascend by subtracting the final depth from the starting depth: Distance ascended = Starting depth - Final depth = -150 m - (-46 m) = -150 m + 46 m = 104 m.
2. Next, divide the total distance by the rate of ascent: Time = Distance ascended / Rate of ascent = 104 m / 8 m per minute.
3. Perform the division to find the time: Time = 13 minutes.

The submarine will take 13 minutes to reach a depth of -46 meters.
