Answer 1

$\huge\sf\orange{☞Given }$

A submarine goes 50 m into the sea from sea level after every 3 minutes, how much deep will the submarine go after half an hour?

______________________

$\huge\sf\green{☞To Find:-}$

A submarine goes deep in 3 minutes = 50 m

How many times deep will submarine go = 30 ÷ 3 = 10 times

A submarine goes deep in half hour ( 30 min)= 50 × 10 = 500 m

${\huge{\boxed{\mathcal{\orange{so,the \: answer \: is \: 500 m }}}}}</p><p></p><p></p><p>$

Answer 2

Answer:

500 meters.

Step-by-step explanation:

Given:- A submarine goes 50 m deep into sea after every 3 minutes.

To Find:- Distance submarine will go after half an hour.

Solution:-

We know that, 1 hour = 60 minutes.

                    ∴  0.5 hour = (60 × 0.5) minutes

                                       = (60 × 5) ÷ 10 mins

                                       = 30 minutes.

Acc. to the question,

Submarine goes 50 m deep after every 3 minutes.

So in 1 minute the submarine will go 50/3 m deep.

Therefore, in 30 minutes it will go = (50 × 30) ÷ 3 meters.

                                                        = 1500 ÷ 3 meters.

                                                        = 500 meters.

Therefore, in half an hour the submarine will go 500 meters deep.
