Answer:

$Depth = 100m$

Step-by-step explanation:

Given

Initial Level = 340 m

Number of stages = 4

Difference in each stage = 60 m

Required

Determine the depth of the submarine after 4 stages

First, we have to calculate the total distance moved towards the surface of the sea;

This is calculated as

$Total\ Distance = Number\ of\ Stages * Difference\ in\ each\ stage$

$Total\ Distance = 4 * 60m$

$Total\ Distance = 240m$

This implies that the submarine moved a total distance of 240 metres;

It;'s new depth is calculated as follows;

$Depth = Initial\ Depth - Total\ Distance$

$Depth = 340m - 240m$

$Depth = 100m$

<em>Hence, its new depth after 4 stages of rising is 100m</em>

How do I do this please help

Umnica [9.8K]

Answer:

wrong as his calculation was incorrect at initial level itself when he found the result of the division

Step-by-step explanation:

Andre said

3 ÷ $\frac{2}{3}$

$=3 \times \frac{3}{2}$

$=\frac{3 \times 3}{2}$

$=\frac{9}{2}$

but andre calculated it as

$=4\tfrac{1}{3}$

$=\frac{4 \times 3 + 1}{3}$

$=\frac{13}{3}$

Hence his calculation was incorrect at initial level itself
