Questions and formulas:
Question: Which elevation groundstation has a capacity in persons/hour larger than 820, and a Name or route of lager 1, and a slope length smaller than 336?
Formula: AVERAGE(FILTER(C1,(F1>820)*(A1="lager 1")*(E1<336)))
Formula2: AVERAGE(FILTER(C2:C15,(F2:F15>820)*(A2:A15="lager 1")*(E2:E15<336)))
Level: easy
Question: Which slope length has a type of surface lift, and an elevation groundstation smaller than 1974, and a construction year(s) of 1971, and a Name or route of alpmatten 1?
Formula: FILTER(E1,(B1="surface lift")*(C1<1974)*(G1="1971")*(A1="alpmatten 1"))
Formula2: FILTER(E2:E15,(B2:B15="surface lift")*(C2:C15<1974)*(G2:G15="1971")*(A2:A15="alpmatten 1"))
