Answer:

200

Step-by-step explanation:

S_{n} = \frac{n}{2} ( f + l) ← f is the bottom layer anf f the top layer, thus

S_{8} = \frac{8}{2} (39 + 11) = 4 × 50 = 200

So you’d add 5 and 3 so it’s 8 ft/s

You then divide 220/8

So it should be 27.5 seconds.

Sorry about that other guy. Hope this helps!
