The answer is 15 miles total.

To find out her distance per minute for each you divide time by distance of her training activity.

Biking: $\frac{300}{75} = 4$ $300/75=4$ minutes per mile

Running: $\frac{240}{30} = 8$ $240/30=8$ minutes per mile

Then you divide the time she spends by the minutes per mile for each.

Biking: $\frac{48}{4} = 12$ $48/4=12$ miles

Running: $\frac{24}{8} = 3$ $24/8=3$ miles

$12 + 3 = 15$ $12+3=15$ miles
