It would be 1/4 because you would change them to a common denominator then simply them and you get 1/4
Substitute , so that . Then the ODE is equivalent to
which is separable as
Split the left side into partial fractions,
so that integrating both sides is trivial and we get
Given the initial condition , we find
so that the ODE has the particular solution,
Step-by-step explanation:
17². + 144²=x²
289 + 20736=x²
x²=21025
x =√21025
x=145
145 miles apart
