Question

The distance between two stations is 180 km. A train takes 2 hours to cover this distance. The speed of the train in m/sec is......please help i rlly need it ....Please

Answer 1

Av = 25 [m/s]

Step-by-step explanation:

To solve this problem we must use the definition of speed, which is defined as the relationship between distance over time. for this case we have.

`Av=(distance)/(time)`

where:

Av = speed [km/h] or [m/s]

distance = 180 [km]

time = 2 [hr]

Therefore the speed is equal to:

`Av = (180)/(2) \\Av = 90 [km/h]`

Now we must convert from kilometers per hour to meters per second

`90[(km)/(h)]*1000[(m)/(1km)]*1[(h)/(3600s) ]= 25 [m/s]`
