GAMING In a video game, the user navigates a character across an unknown land using a map. On the map, the distance between the
soldi70 [24.7K]

The question is an illustration of scale drawing

The character have to travel 8.5 km in the game to visit all three destinations and return to their starting point

<h3>How to calculate the actual distance</h3>

The distance on the map are given as:

A =2 cm

B = 8 cm

C = 7 cm

The total distance on the map would be:

Total =2cm + 8cm + 7cm

Total =17cm

The actual distance between the store and the dungeon is 4 kilometers.

This means that:

B' =4km

So, we have:

Scale = B : B'

Scale = 8cm : 4km'

Represent the required actual distance with x.

So, we have:

17cm : x = 8cm : 4km

Express as fraction

\frac{x}{17} = \frac 48

Multiply both sides by 17

x = \frac 48 * 17

x = 8.5

Hence, the actual distance travelled is 8.5 km

Express in the form n:1 give n as a decimal 21:12
Makovka662 [10]

1.75:1 which is similar to n:1 where n=1.75

<u>Step-by-step explanation:</u>

Here we have to Express in the form n:1 give n as a decimal 21:12 . Let's find out:

Given ratio as 21:12 . Let's convert it into n:1 , where n is decimal

⇒ 21:12

⇒ \frac{21}{12}

⇒ \frac{3(7)}{3(4)}

⇒ \frac{7}{4}

⇒ \frac{\frac{7}{4}}{\frac{4}{4}}                      { dividing denominator & numerator by 4 }

⇒ \frac{\frac{7}{4}}{1}

⇒ \frac{1.75}{1}

⇒ 1.75:1 which is similar to n:1 where n=1.75
