Answer:

Step-by-step explanation:
we know that

when
-------> complementary angles
so


Because
-------> complementary angles
In this problem the product of

is equal to

therefore

We Know, distance = speed * time
d = 15.5 * 2.5
d = 38.75 miles
In short, Your Answer would be 38.75 miles
Hope this helps!
