Question

The distance between Delhi and Lucknow is 495 km. How much time will a train take to cover this distance at an average of 99 km/ h?

Answer 1

Answer:

time =distance/speed

495/99=5hr

Answer 2

Answer:

The train will take $5$ $hours$ to cover the distance.

Explanation:

• The time taken to cover a distance depends on the speed and the distance between the two locations.
• The total distance traveled divided by the total time of journey gives the average speed.

Step 1:

The formula for the time taken is :

$Time=\frac{D}{S}$

where, $D$ is the total distance traveled

            $S$ is the average speed.

It is given that the distance between Lucknow and Delhi, $D=495$ $km$

The average speed of the train, $S=99$ $km/h$

Step 2:

The time taken by the train is $=\frac{495 km}{99 km/h}$

                                                  $= 5$ $hours$

So, the train will take $5$ $hours$ to cover the distance.
