- Five friends, Alice, Bob, Carol, David and Eve, visited different attractions, Star Peak, Crystal Cove, Emerald Falls, Thunder Ridge and Mystic Valley, not necessarily in the same order. They each paid different amounts for their entry tickets, $\$20, \$40, \$60, \$80$ and $\$100$. Here are some clues:
-Alice paid $\$40$ for her entry ticket.
-The cost of admission to Emerald Falls was $\$40$ less than to Thunder Ridge.
-Carol paid $\$40$ more than David did for their entry tickets.
-The five different attractions visited are: Crystal Cove, the attraction where the entry ticket cost was $\$40$, the attraction where the entry ticket cost was $\$100$, the attraction with a $\$20$ entry ticket, and the attraction Carol visited.
-Eve visited Star Peak.
How much (in $\$$) was the entry ticket to Emerald Falls? - Lily and Jake started jogging on a circular track with a circumference of 308 metres from the same starting point at the same time. Lily jogs for the first 120 metres with a speed of $6\text{ m/s}$, then continues for the next 200 metres with a speed of $4\text{ m/s}$, repeating this pattern. Jake jogs with a constant speed of $5\text{ m/s}$ but in the opposite direction. How many metres has Lily jogged from the same starting point by the time they meet for the fourth time? Round your answer to the nearest integer.
