Question

Rhys has a suitcase weighing 22,900 g. Lucy has a suitcase weighing 23,009 g. The weight limit for a flight is 23 kg. Which suitcases are above the limit?

1) Rhys' suitcase
2) Lucy's suitcase
3) Both suitcases
4) Neither suitcase

Answer 1

After converting the weight of the suitcases from grams to kilograms, we find that Rhys' suitcase weighs 22.9 kg, which is below the limit, and Lucy's suitcase weighs 23.009 kg, which is above the flight's weight limit of 23 kg.

Step-by-step explanation:

The question asks which suitcase is above the weight limit for a flight if the limit is 23 kg. Rhys has a suitcase weighing 22,900 g, and Lucy has one weighing 23,009 g. We need to convert the weight from grams to kilograms to determine if the suitcases are over the weight limit of 23 kg. Recall that 1 kg is equivalent to 1,000 g.

To solve each problem, we first convert the weights of the suitcases to kilograms: Rhys' suitcase is 22,900 g / 1,000 g/kg = 22.9 kg, and Lucy's suitcase is 23,009 g / 1,000 g/kg = 23.009 kg. Comparing these weights to the flight's weight limit, Rhys' suitcase is below the limit, whereas Lucy's suitcase is above the limit as it exceeds 23 kg, even if only slightly.

Therefore, the correct answer to the question is option 2) Lucy's suitcase.
