It takes 8 people to pull a 16 ton truck. How many people would it take take to pull a 60 ton truck? I got 30 people am I right? If not can you tell me the answer with work? (:

Answers

8 people pull a 16 ton truck
we can make that a proportion
8:16 
which can be reduced to 
1:2 

that means 1 person can pull 2 tons

to pull a 60 ton truck, you would have a proportion of
x: 60 = 1:2

cross multiply and you get

60 = 2x
x = 30

yes, you're right!
