Two cranes are lifting 100 tons. If crane A has 40% of the load, how much weight will crane B have on its hook?

To determine how much weight crane B will have on its hook, we start by noting the total load being lifted, which is 100 tons. To convert this weight into pounds, we use the conversion factor where 1 ton is equal to 2,000 pounds. Therefore, 100 tons translates to 200,000 pounds (100 tons x 2,000 lbs/ton).

Next, since crane A is responsible for 40% of the total load, we can calculate the weight that crane A is lifting. Multiplying 200,000 pounds by 40% (or 0.40) gives us 80,000 pounds (200,000 lbs x 0.40).

Now, to find out how much weight crane B will have on its hook, we simply subtract the weight being lifted by crane A from the total weight. This calculation is as follows:

200,000 pounds (total load) - 80,000 pounds (crane A's load) = 120,000 pounds.

Thus, crane B is lifting 120,000 pounds. This confirms that the correct choice reflects the calculation performed based on the distribution of the load between the two cranes. The reasoning highlights the importance of understanding load distribution principles
