Question

Un tren recorre 200 km en 3h 25 min 15s.¿cual es su velocidad ?

Answer 1

velocidad = distancia / tiempo
v = d/t
t  3 horas 25 min 15s
1hora = 3600s
3horas = 3600*3= 10800s

1min = 60s
25 min = 25*60 = 1500s
t= 10800s +1500s +15s= 12315s

d = 200km = 200*1000= 200000m

v = 200000m/12315s
v =16,24m/s
