It will be 90 feet considering the water triangle as shown as the figure
In general: <span>(a - b)^3 = a^3 - 3 a^2b + 3 a b^2 - b<span>^3
(4x-2y)^3 = </span></span>(4x)^3 - 3 (4x)^2(2y) + 3 (4x) (2y)^2 - (2y)^3
Answer:
3rd option
Step-by-step explanation:
you would multiply speed by time
20 feet per second times 10 seconds = 200 feet total
