imagine que, de um terminal rodoviário, partam
os ônibus de três empresas A, B e C. Os ônibus da
empresa A partem a cada 15 minutos; da empresa B,
a cada 20 minutos; da empresa C, a cada 25 minutos.
Às 7 h, partem simultaneamente 3 ônibus, um de
cada empresa. A próxima partida simultânea dos
ônibus das 3 empresas será às
a) 9 h.
b) 9 h e 50 min.
c) 10 h e 30 min.
d) 11 h.
e) 12 h.
