Question

A) Solve the numericale
1) A train covers a distance of 1800 koma in 10 hours, Calculate its speed and express it in the M.K.S system​

Answer 1

Answer:

180km/h

Explanation:

distance covered by train =1800km

time taken =10h

speed=. Distance/time taken

1800/10

= 180km/h

Answer 2

Given,

Total distance covered by a train = 1800 Km

Duration of the journey = 10 hours

To find,

Speed of the train in M.K.S system.

Solution,

We can simply solve this numerical problem by using the following process:

Mathematically,

speed (s)

= distance traveled (d) / time of journey(t)

Also,

In the M.K.S system, speed is expressed in the form of meter/second.

1 kilometer = 1000 meters

1 hour = 60 minutes = 3600 seconds{Equation-1}

Now, according to the question;

Speed of the train in M.K.S system

= distance traveled (d) / time of journey(t)

= 1800 Km x 10 hours

= (1800 × 1000) meters x (10 × 3600) seconds

= 50 m/s

Hence, the total speed of the train in the M.K.S system is equal to 50 meters/second.
