Answer 2

Calculating the Number of Trucks Needed for Grain Transportation

To calculate the number of trucks with a capacity of 4.5 tons needed to transport the same amount of grain that required 9 trucks with a capacity of 7.5 tons, we can use the following approach:

1. Calculate the Total Weight of the Grain: - The total weight of the grain can be calculated by multiplying the number of trucks by their respective capacities.

2. Determine the Number of Trucks with 4.5 Tons Capacity: - Once we have the total weight of the grain, we can then calculate the number of trucks with a 4.5-ton capacity needed to transport the same amount of grain.

Let's proceed with the calculations.

Calculation Steps

1. Calculate the Total Weight of the Grain: - The total weight of the grain that required 9 trucks with a capacity of 7.5 tons can be calculated as follows: - Total weight = Number of trucks * Capacity per truck - Total weight = 9 trucks * 7.5 tons/truck - Total weight = 67.5 tons

2. Determine the Number of Trucks with 4.5 Tons Capacity: - To transport the same amount of grain using trucks with a 4.5-ton capacity, we can calculate the number of trucks needed as follows: - Number of trucks = Total weight / Capacity per truck - Number of trucks = 67.5 tons / 4.5 tons/truck - Number of trucks = 15 trucks

Answer

To transport the same amount of grain, it would require 15 trucks with a capacity of 4.5 tons each.

The calculations show that 15 trucks with a capacity of 4.5 tons each would be needed to transport the same amount of grain that required 9 trucks with a capacity of 7.5 tons.
