Question

A train is moving at a speed of 100 km/h. How much time will it take to cover a distance of 20 km ?​

Answer 1

Answer:

speed = distance / time .. 100= 20/t .... t = 20÷100 0.2 minute so time = 12 hrs Or 0.2

Answer 2

Answer :

Time taken by the train is 0.2 hours.

Step-by-step explanation :

To Find,

• How much time taken by the train ?

Given that,

• Speed of the train = 100 km/h

• Distance required to travel = 20 km

Solution,

As we know that,

Time taken = Distance travelled / Speed

Therefore, by putting the values,

Time taken = 20 / 100

Cancelling the first zeros from both the sides.

= 2 / 10

Dividing 2 and 10 with 2

= 1 / 5 hours or 0.2 hours.

∴ Hence, time taken by the train is 0.2 hours.

Some more important rules,

• Speed = Distance / Time
• Distance = Speed × Time
• Time = Distance / Speed
