Answer:

Yes, 15 miles.

Explanation:

You need to use proportions. For example with biking:


(48)/(300) = (b)/(75)

Using cross products:


300b = 48(75)


300b = 3600


b = (3600)/(300) = 12

The same is true for running:


(24)/(240) = (r)/(30)


(1)/(10) = (r)/(30)


10r = 1(30)


10r = 30


r = 3

The total distance is the sum of these two:


d = b + r = 12 + 3 = 15
