Question

An airplane flies at a speed of \[474\] per hour. How many miles does the plane fly in \[5\] hours?

Answer 1

Hint: In this question, they have given that an airplane flies at a speed of \[474\] per hour and asked us to find how many miles does the plane fly in \[5\] hours. Since they have given the speed per hour, we will simply have to multiply it with $ 5 $ . Since the airplane is flying at a constant speed, the given data is proportionate to each other. So we can also use this method to solve the given question. Further, we simplify we get the required answer.

Complete step by step answer:
In this question, they have given that an airplane flies at a speed of \[474\] per hour and we need to find the distance it covers in \[5\] hours. It will obviously \[5\] times more than one hour.
Distance covered by the airplane in one hour= \[474\]
So, distance covered by the airplane in five hours = $ 474 \times 5 $
On multiply the two term and we get,
$ \Rightarrow 2370 $

Therefore miles covered by the airplane in five hours is $ 2370 $ .

Note: In this question we have a alternative method as follows:
Alternative method:
Since the airplane is flying at a constant speed, the given data must be proportionate to each other.
Let us assume the distance or miles covered by the airplane in five hours as $ x $
Therefore \[474\] in an hour is proportional to $ x $ in five hours.
It can be written as

$ 474{\text{ }} $	$ 1 $
$ x $	$ 5 $

So now, this can be cross multiplied in order to find $ x $ since they are proportionate.
Cross multiplying this, and we can write it as
$ x = 474 \times 5 $
On multiply the term we get the value of $ x $ ,
That is equal to $ 2370 $ .
Therefore the total distance covered by the airplane in five hours is $ 2370 $
