Question

an aeroplane flies at a speed of 630 km per hour for 2.5 hours how much distance does the airplane cover

Answer 1

Speed = 630 km/hr
Time = 2.5 hr
Now,
Distance = speed/time
=630/2.5
=252km Ans.

Answer 2

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

Given :

• speed of an airplane = 630km/h
• Time=2.5hrs

To find :

• Distance covered by plane

Solution :

$\fbox{Formula used :}$

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

Speed=630km/h

Time=2.5hrs

Inserting values in formula :

$\tt\ :⟶d = 1240\times 2.5 km$

$\tt\ :⟶d = 3100 km$

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

$\tt\ :⟶d = 3100 ×1000m$

$\tt\ :⟶d = 3.1×1000000 m$

$\tt\ :⟶d = 3.1×10^6 m$

$\bf\purple{ d = 3100 km\:or\:3.1×10^6m }$
