Question

A car covers a distance in 40 minutes with an average
speed of 60 km per hour. The average speed to cover the
same distance in 30 minutes is एक कार 40 मिनट में 60 किमी
प्रति घंटे की औसत गति के साथ दूरी तय करती है। 30 मिनट में समान दूरी
तय करने की औसत गति है​

Answer 1

Answer:

Mark me as a Brain list

Step-by-step explanation:

Let the distance traveled be 'x' km. Then the average speed is given by, Therefore, the average speed to cover the same distance time taken by the car in 25 min is 96 km/hr.

Answer 2

Step-by-step explanation:

Given :

A car covers a distance in 40 min with an average speed of 60 km/h.

To find :

What should be the average speed to cover the same distance time taken by the car in 30 min ?

Solution :

Let the distance traveled be 'x' km.

Time taken = 40 minutes = {2}/{3} hrs

Average speed = 60 km/hr

The distance formula = Speed×Time

= 60× 2/3

= distance= 40 km.

Now, the time is 30 minute = 1/2 hrs

Then the average speed is given by,

Speed= distance/ time

40/ 1/2

= 80 km / hr

Therefore, the average speed to cover the same distance time taken by the car in 30 min is 80 km/hr.
