Answer:
Ski Lift C is the fastest one as it has a rate of [tex]12ft/s[/tex], the highest above the three
Step-by-step explanation:
Ski Lift A Rate
[tex]SL_{A}=\frac{1200feet}{2min}[/tex], or in seconds [tex]SL_{A}=\frac{1200feet}{120s}=10ft/s[/tex]
Ski Lift B Rate
[tex]SL_{B}=\frac{1500feet}{3min}[/tex], or in seconds [tex]SL_{B}=\frac{1500feet}{180s}=8.33ft/s[/tex]
Ski Lift C Rate
[tex]SL_{C}=\frac{1800feet}{2\frac{1}{2} min}[/tex], or in seconds [tex]SL_{C}=\frac{1800feet}{150s}=12ft/s[/tex]
As we can see the Ski Lift with the highest rate is the C.
