There are 26 trucks, each with a 4-ton payload, are needed to unload a freight train. How many trucks with a 6.5-ton payload would be needed to do the same job?

16

Step-by-step explanation:

Lets first start off with what we know. We know that if we have 26 trucks with a 4-ton payload each, we will be able to unload a freight train. In total, unloading a freight train will require a 104-ton payload because ...

(26 trucks) x (4-ton payloads) = 104 tons

Since we know that a freight train can carry 104 tons, we can just do some simple math to figure out the rest of the problem.

(? trucks) x (6.5-ton payloads) = 104 tons

All we do now is divide 104 by 6.5 to get our answer.

104 / 6.5 = 16
