E is correct
90% of 100 = 0.9 x 100 = 90

Answer: The visitor can see 90 ships.

Using the 2nd row it traveled 120 miles in 3 hours
so 120/3 = 40 miles per hour
so distance (d) = 40h
The correct answer is option C.
The solution is shown below:
(8 - 3i)(6 + 5i)
= 8(6 +5i) - 3i(6 + 5i)
= 48 + 40i - 18i - 15i²
= 22i + 48 - 15(-1)
= 22i + 48 + 15
= 22i + 63
= 63 + 22i
