A map has a scale of 3 cm : 18 km. If Riverside and Smithville are 54 km apart then they are how far apart on the map?
rainliest plz solve

Answers

Riverside and Smithville will be 9 km apart on the map. For every 6 km they will be 1 cm apart on the map.

54 km is 3 times of 18km and 3 times of 3 cm is 9 cm. So, Riverside and Smithville are 9 cm apart on the map.

Ratio and proportion:

Important information:

The given scaling ratio is 3 cm : 18 km.Riverside and Smithville are 54 km apart.

We need to find the distance between Riverside and Smithville in the map.

Let x cm be the distance between Riverside and Smithville in the map. The distance in the map and the actual distance are always proportional.

[tex]\dfrac{x}{54}=\dfrac{3}{18}[/tex]

[tex]x=\dfrac{3}{18}\times 54[/tex]

[tex]x=9[/tex]

Therefore, Riverside and Smithville are 9 cm apart on the map.

Step-by-step explanation:

4 x 2 =8

3 x 2= 6

Answer:

[tex]x = 6[/tex]

Step-by-step explanation:

What I would do in this case is cross multiply, although there are other strategies. I will explain cross multiplication here. In cross multiplication you multiply the denominater and numerator of different fractions on each side of the equal sign. So for this problem you would multiply 4 and X, denominator of the first number and numerator of the second. Then you would multiply the numerator from the first fraction, 3, and denominator from the second, 8.

[tex]4 \times x = 4x \\ 3 \times 8 = 24 \\ \\ so \: 4x = 24[/tex]

Now we can solve for x.

[tex]4x = 24 \\ \div 4 \\ x = 6[/tex]
