In a hotdog eating competition, the first competitor can eat 10 hot dogs per minute. The second competitor can eat 3 times more than the first competitor, while the third competitor can eat twice as much as the second competitor. How many hotdogs can the third competitor eat after 5 minutes?
The second competitor can eat 10 x 3 = <<10*3=30>>30 hotdogs per minute.
The third competitor can eat 30 x 2 = <<30*2=60>>60 hot dogs per minute.
Therefore, the third competitor can eat 60 x 5 = <<60*5=300>>300 hot dogs after 5 minutes.
