2240lb:______kg
a) 1016kg
b) 1020kg
c) 1012kg
d) 1024kg

Answer 1

To convert 2240 pounds to kilograms, divide by the conversion factor of 2.2 pounds per kilogram. The closest approximation to the result is 1020 kg.

The correct answer is B.

Step-by-step explanation:

To convert a long ton, which is 2240 pounds, into kilograms, we use the conversion factor that 1 kilogram is about 2.2 pounds. By dividing 2240 pounds by 2.2, we can find the equivalent mass in kilograms.

2240 lb ÷ 2.2 lb/kg = 1018.18 kg

Looking at the provided options, while none of them is exactly 1018.18, option (b) 1020 kg is the closest approximation.
