Final answer:
Mrs. Kurz swims 2 lengths of the swimming pool per minute since she swims half the length every quarter of a minute. Therefore, the correct option in the final answer is (c) 2.
Step-by-step explanation:
The question asks us to calculate how many swimming pool lengths Mrs. Kurz swims per minute given that she swims half the length of the swimming pool every quarter of a minute. To solve this, we break down the problem into smaller parts.
Since there are 4 quarters in a full minute, we multiply the distance she swims in one quarter (half the length) by 4. Doing this, we conclude that Mrs. Kurz swims:
0.5 length/quarter-minute × 4 quarter-minutes/minute = 2 lengths/minute. Therefore, the correct option in the final answer is (c) 2.
