Answer :
Final answer:
The answer involves simple addition. Convert the given time difference 5 3/10 seconds to a decimal (5.3 seconds) and add it to Darrell's time of 44.7 seconds. This results in 50 seconds for Zack's time, which unfortunately doesn't match any of the provided options.
Explanation:
The subject of this question is Mathematics, specifically a type of problem solving within the topic of speed, distance, and time. This is a standard arithmetic problem. Darrell completed a 400m race in 44.7 seconds, and Zack ran the same race but finished 5 3/10 seconds faster. To determine how fast Zack ran the race, we need to add Darrell's time and the time difference.
First, convert the mixed number 5 3/10 to a decimal, which results in 5.3 seconds. Then add this to Darrell's time of 44.7 seconds:
44.7 seconds (Darrell's time) + 5.3 seconds (time difference) = 50 seconds.
However, this seems to not match any of the provided options (a) 39.4 seconds (b) 49.4 seconds (c) 42.7 seconds (d) 44.0 seconds. There may be a mistake in the question as Zack, who ran slower than Darrell, can't have a time less than 44.7 seconds.
