Question

if a plane travels 7040 km in 10 hours ,how long will it take to cover distance os 3520 km?​

Answer 1

Answer:

5 hours

Step-by-step explanation:

According to the information provided in the question following data is given as follows

Plane travels 7040 km  in 10 hours

We need to find the time to cover  the distance 3520 km

Speed of plan =7040 km /10 hours

Firs we find the speed in km /hour

7040 Km =10 hours

3520 Km=x

Let x is the time taken to to cover a distance of 3520 km

So simply cross multiplication we get the answer

$7040=10\\3520=x$

Hence

$7040 x =3520 \times 10\\7040x=35200\\x=\frac{35200}{7040} \\x=5 hours$

As x is the time taken to cover a distance of 3520 km hence it takes

5 hours

Answer 2

Answer:

Plane takes $5\ hr$ to cover distance of $3520 \ km$ .

Step-by-step explanation:

To find : time taken by plane to cover distance of $3520 \ km$ .  

Given :  plane travels 7040 km in 10 hours .

Solution :

• As per given data we know that plane travels $7040$ km in $10$ hours . We have to find time taken by plane to cover distance of $3520 \ km$ .  
• Firstly we find speed of plane by using formula -

        $Speed = \frac{Distance }{Time }$

• $Speed = \frac{7040\ km}{10\ hr }$

                 $= 704 \ km /hr$

• Now , to find time taken by plane to cover distance of $3520 \ km$ .  
• We substitute values in following formula ,
• $Time = \frac{Distance }{Speed}$

                  $= \frac{3520\ }{704} \\\\= 5 \ hr$
