Answer:
45 miles.
Step-by-step explanation:
We have been given that Taylor and Anya live 63 miles apart.
Taylor rides at the rate of 12.5 miles per hour, therefore, distance covered by Taylor in 1 hour will be 12.5 miles.
Anya rides at the rate of 5.5 miles per hour, therefore, therefore, distance covered by Taylor in 1 hour will be 5.5 miles.
Now let us find total distance covered by Anya and Taylor.

To find the distance between Anya and Taylor after one hour we will subtract distance traveled by Anya and Taylor in one hour from 63.


Therefore, Anya and Taylor are 45 miles apart after one hour of riding.
