How far did the Smiths drive from 8 a.m. to 8:20 a.m.; i.e., in 20 minutes?

distance = rate*time.

d = 48mi/hr * 1/3 hr = 16 miles which the Smiths had as a head start.

let x = distance driven by Garcias. time = d/r = x/60.

time for Smiths = x-16 is distance driven. time = (x-16)/48.

Set time = time or

x/60 = (x-16)/48

solve for x.

That will be the distance. Plug that into x/60=time and calculate time. Add that to 8:20 to know the final time at which both reached the same point. Post you work if you run into trouble.
