When the moving sidewalk at the airport is broken, as it often seems to be, it takes you 54s to walk from your gate to the baggage claim. When it is working and you stand on the moving sidewalk the entire way, without walking, it takes 83s to travel the same distance. How long will it take you to travel from the gate to baggage claim if you walk while riding of the moving sidewalk?
Accepted Solution
A:
Answer:Your travel time will be 32.71 secs.Step-by-step explanation:Let the total distance be x feet.Speed while walking = [tex]\frac{x}{54}[/tex] feet per secondSpeed on the sidewalk = [tex]\frac{x}{83}[/tex] feet per secondTherefore, total speed while walking on moving sidewalk =[tex]\frac{x}{54} +\frac{x}{83y}[/tex]= [tex]\frac{83x+54x}{54\times83}[/tex]= [tex]\frac{137x}{4482}[/tex] = [tex]\frac{x}{32.71}[/tex] Hence, your travel time will be 32.71 secs.
