# Speed of Slovakian trains

Rudolf decided to take the train from the station 'Trnava' to 'Zemianske Kostoľany'. In the train timetables found train R 725 Remata :

Calculate the average speed between these stations, travel distance and time.

Result

s =  99 km
t =  2 h
v =  49.5 km/h

#### Solution:

$s=145-46 = 99 \ \text{ km }$
$t=(15-13)+(32-32)/60 = 2 \ \text{ h }$
$v=(145-46)/((15-13)+(32-32)/60) = \dfrac{ 99 }{ 2 } = 49.5 \ \text{ km/h }$

Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
