Answer:
Yes, 15 miles.
Step-by-step explanation:
You need to use proportions. For example with biking:
[tex]\frac{48}{300} = \frac{b}{75}[/tex]
Using cross products:
[tex]300b = 48(75)[/tex]
[tex]300b = 3600[/tex]
[tex]b = \frac{3600}{300} = 12[/tex]
The same is true for running:
[tex]\frac{24}{240} = \frac{r}{30}[/tex]
[tex]\frac{1}{10} = \frac{r}{30}[/tex]
[tex]10r = 1(30)[/tex]
[tex]10r = 30[/tex]
[tex]r = 3[/tex]
The total distance is the sum of these two:
[tex]d = b + r = 12 + 3 = 15[/tex]
