Ms. Driva Reck drove from her home to a service station at 48km/h. She returned home by bicycle at 16km/h. The entire trip took 4 hours. How far was the service station from Ms. Reck's home?

time on bike  t hours
time driving  4t hours
16t = 48(4t)
16t = 192  48t
64t = 192
t = 3
so distance = 3(16) = 48 km
