Question

An aeroplane covers a distance of 21,744 km in 24 hours. Find its speed in
kilometers per hour?​

Answer 1

Answer:

Solution=aeroplane distance =21,744

hours =24

21,744÷24=906

So, 906 km in 1 hours

Answer 2

Given :

• Distance covered by an aeroplane = 21,744 km

• Time taken to cover 21,744 km = 24 hrs

‎

‎

To find :

• The speed of the aeroplane in kilometers per hour.

‎

Solution :

We know,

$\bf\color{black}{\maltese}$ $\bf\color{purple}{Speed~=~\frac{distance}{time}}$

‎

Plugging the given values in the formula

$\sf\implies\:Speed~of~an~aeroplane~=~\frac{21,744~km}{24~hr}$

Reducing the fraction to lower terms

$\sf\implies\:Speed~of~an~aeroplane~=~\cancel{\frac{21,744~km}{24~hr}}$

$\sf\implies\:Speed~of~an~aeroplane~=~\cancel{\frac{10,872~km}{12~hr}}$

$\small{\underline{\boxed{\mathrm{\implies~Speed~of~an~aeroplane~=~906~km~per~hr}}}}$

$\sf\therefore~The~speed~of~the~aeroplane~is~906~km~per~hr$ .

Some more formula :‎

• Distance = speed × time
• Time = distance / speed
• Speed = distance / time
