a college swimmer is the anchor (last) leg of the womens 4x100 meter medley relay. the first swimmers split was 48.23 seconds, the second split was 49.04 seconds, and the third split was 51.62 seconds. how much time does the anchor swimmer have to cover the 100 - meter split to be the schools record of 3 minutes and 19.10 seconds?\na. 47.51 seconds\nb. 49.15 seconds\nc. 40.81 seconds\nd. 50.21 seconds\ne. 51.70 seconds

Answer

# Explanation: ## Step1: Convert total record time to seconds 1 minute = 60 seconds, so 3 minutes and 19.10 seconds is \(3\times60 + 19.10=180 + 19.10 = 199.10\) seconds. ## Step2: Calculate sum of first - three swimmers' splits The sum of the first swimmer's split (48.23 seconds), the second swimmer's split (49.04 seconds), and the third swimmer's split (51.62 seconds) is \(48.23+49.04 + 51.62=148.89\) seconds. ## Step3: Find time for anchor swimmer Subtract the sum of the first - three swimmers' splits from the total record time. So the time for the anchor swimmer is \(199.10−148.89 = 50.21\) seconds. # Answer: D. 50.21 Seconds
