***
let x=time Sandy ran
8-x time Sandy rode
distance=speed*travel time
8x=24(8-x)
8x=192-24x
32x=192
x=6
8-x=2
time Sandy ran=6 hrs
time Sandy rode=2hrs

-----------------
Avg speed for the round trip is
2*8*24/(8 + 24) = 384/32
= 12 mi/hr
-------
12 mi/hr * 8 hrs = 96 miles
She ran 48 miles, rode 48 miles
