Question

a train runs at 45 km per hour how far does it goes in 6 seconds

Answer 1

75 meters/6 seconds
convert km into meters 
= 45000meters
time=45000/(60*60)
=12.5
6 sec 
=12.5*6
= 75meters

Answer 2

Answer:

The distance is 75 m.

Step-by-step explanation:

Given : A train runs at 45 km per hour in 6 seconds.

To find : How far does it goes?

Solution :

Speed of the train = 45 km/hr

Covert into m/s, multiply with $\frac{5}{18}$

$45 km/hr=45\times \frac{5}{18}=12.5 m/s$

Time = 6 seconds

Now, The formula is

$\text{Distance}=\text{Speed}\times \text{Time}$

$\text{Distance}=12.5\times 6$

$\text{Distance}=75 m$

Therefore, The distance is 75 m.
