The height of a model rocket is 4.5% of the height of the actual rocket.The model is 1.22 m high.How high is the actual rocket
Serjik [45]

Answer:

Actual Height = 27.11 m

Step-by-step explanation:

Given:

Height of model rocket = 4.5 % of actual Height

Model Height = 1.22 m

To Find:

Actual Height of rocket = ?

Solution:

We have to Find the Actual Height of the rocket

Let actual height be x

Now it is given that

Height of model rocket = 4.5 % of actual Height

As we have the values so putting it in it becomes

1.22 = 4.5 % * x

it could be written as

1.22=\frac{4.5}{100}*x

Multiplying both sides by \frac{100}{4.5}

it becomes

1.22*\frac{100}{4.5} = x

\frac{122}{4.5} = x

27.11 m =x

or

Actual Height = 27.11 m
