Which scenario matches the given expression?

Question


 A.
On the first day of mining a metal, a miner goes  of a kilometer below ground level. On the second day, he goes  of a kilometer below ground level. How many times further below ground level does the miner go on the second day than on the first day?
 B.
Rick spent  of an hour studying. Later, he spent  of an hour watching television. How much more time did Rick spend studying than watching television?
 C.
A builder uses  of an acre of land for constructing a building. He uses  of an acre of land for a garden. How much more of an acre does he use for the building than the garden?
 D.
A tuna swims  of a meter below sea level. A sardine swims  of a meter below sea level. How many times more below sea level does the sardine swim than the tuna?

Answer 1

To determine which scenario matches the expression, we need to look for an instance involving a comparison of two quantities where we express how much more one is than the other or how many times one number is relative to another.

Let's analyze each scenario:

A. This scenario asks how many times further below ground level the miner goes on the second day compared to the first day. This implies a ratio or division of the two values.

B. This scenario compares how much more time Rick spent studying than watching television. This suggests a direct subtraction of the two times, not a ratio.

C. Similar to scenario B, this scenario compares how much more land the builder uses for the building compared to the garden. This involves subtraction to find the difference.

D. In this scenario, it asks how many times more below sea level the sardine swims than the tuna. This requires a division of the two values to determine the ratio of their depths below sea level.

Based on the analysis, scenarios A and D both involve ratios and comparisons of one quantity being a multiple of another. However, only D explicitly states how many times more one quantity is compared to the other, which is consistent with the original expression regarding a relative comparison of two quantities.

Therefore, the answer is: D. A tuna swims  of a meter below sea level. A sardine swims  of a meter below sea level. How many times more below sea level does the sardine swim than the tuna?
