Question

an airplane flies with a constant speed of 800 km per hour. how far can it travel in 12 hours? ​

Answer 1

Answer:

9600km

Step-by-step explanation:

800km×12=9600km

Answer 2

$\sf\huge\bold{Answer:}$

Given :

• speed of an airplane = 800 km/h
• Time=12hrs

To find :

• Distance covered by plane

Solution :

$\fbox{Formula used :}$

$\tt\red{ :⟶distance = speed \times time}$

Speed=800km/h

Time=12hrs

• Inserting values in formula :

$\tt\ :⟶d = \big(800 \times 12 )km$

$\tt\ :⟶d = 9600 km$

$\tt\red{ 1km = 1000m}$

$\tt\ :⟶d = 9600×1000m$

$\tt\ :⟶d = 96×10^5 m$

$\tt\ :⟶d = 9.6×10^6 m$

$\tt\purple{d = 9600 km\: or \: 9.6 × 10^6 }$

Distance covered by plane is 9600 km or $\tt9.6×10^6 m$
