Question

the speed of an 12440 km per hour. find thee distance covered by the airplane in 3 hours 20 minutes

Answer 1

$\textbf {Hey there, here is the solution.}$

.............................................................................................

The speed is 12240 km/h

⇒ 1 hour = 12240 km

..............................................................................................

Convert 3 hours 20 mins into hours:

3 hours 20 mins = 3 20/60 = 3 1/3 hours

.............................................................................................

Find the distance traveled in 3 hours 20 mins:

1 hour = 12240 km

3 1/3 hours = 12240 x 2 1/3

3 1/3 hours = 12240 x 7/3

3 1/3 hours = 28560 km

.............................................................................................

Answer: The plane covered 28560 km in 3 hours 20 mins

Answer 2

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

Given :

• speed of an airplane = 12440 km/h

Time=3hrs20min

To find :

• Distance covered by plane

Solution :

$\fbox{Formula used :}$

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

Speed=12440km/h

Time=3hr+20min

[1min=1/60hr]

=3hr+(20/60)hr

=3hr+⅓hr

=3⅓hr

• Inserting values in formula :

$\tt\ :⟶d = \big(12440 \times 3 \frac{1}{3} \big)km$

• Converting mixed fraction into improper fraction

$\tt\ :⟶d = 12440 \times \frac{3 \times 3 + 1}{3} \: \: \: km$

$\tt\ :⟶d = \big(12440\times \frac{10}{3} \big)km$

$\tt\ :⟶d = \big( \frac{124400}{3} \big)km$

$\tt\ :⟶d = 41466.66...km$

$\tt\ :⟶d ≈ 41466.7 km$

$\tt\purple{d ≈ 41466.7 km}$

Distance covered by plane is 41466.7km
