Step-by-step explanation:
First, we expand the equation:

Then, we combine certain terms in order to simplify them using trigonometry identities.

Note these identities:
Pythagoran relation:

Sum and Difference Formula/Identities:

Thus, if we apply these identities, the simplified equation would be:

Simplying further, the answer would be
Answer:
Daniel is rollerblading at 15 miles per hour
Daniel can go 3 miles in 12 minutes so we do 12÷3 to find out how many minutes it takes to go 1 mile which is 4 now we do 60÷4 to get 15
Alternatively we could do 60÷12 to get 5 then do 3×5 to get 15
