A traveler is walking on a moving walkway in an airport. The traveler must walk back on the walkway to get a bag he forgot. The traveler's ground speed is 1 ft/s against the walkway and 9 ft/s divided by s with the walkway. What is the traveler's speed off the walkway? What is the speed of the moving walkway?

i'm assuming it's looking for the missing length, which should be 4cm

hope this !

step-by-step explanation:

10.50 + taxes which added up to 11.50

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
