Question

7. Anant covers a distance of 225 km in 5 hours in his car. How much distance will he be able to cover in 7 hours? Find the answer using proportions.​

Answer 1

Answer:

Distance covered in

5 hrs = 225 km

1 hr = 225/5

      = 45 km

7 hrs = 45 * 7

        = 315 km

Therefore , He will be able to cover 315 km in 7 hrs

Answer 2

Answer:

Distance covered in 7 hrs. is 315 km.

Step-by-step explanation:

Let distance covered in 7 hrs. be X km.                                                                                                                                                                                                                                

                         Distance (km.)                     Time ( hrs.)

                               225                                   5

                               X                                        7

AS distance and time is directly proportional.

We can write it as,

225 :X : : 5 : 7

According to proportionality rule,

Product of extreme =Product of mean

∴                 225× 7 =  X ×5

 ∴                  1575=5 X

⇒                     X =1575/5

⇒                     X=315
