Final answer:
c) 12 1/2 laps.The total number of laps Michelle ran over four days is 12 1/2 laps, by adding 3 1/2 laps for each of two days and 2 3/4 laps for each of the other two days.
Step-by-step explanation:
The correct answer is option c) 12 1/2 laps. To determine the total laps Michelle ran, we need to add up the laps from each day.
On Monday and Tuesday, she ran 3 1/2 laps each day, which totals 7 laps when added together (3 1/2 + 3 1/2 = 7). On Wednesday and Thursday, she ran 2 3/4 laps each day, which totals 5 1/2 laps when added together (2 3/4 + 2 3/4 = 5 1/2). The sum of laps from Monday to Thursday is therefore 7 laps plus 5 1/2 laps, which equals 12 1/2 laps. Michelle ran a total of 12 1/2 laps over the four days.
To find the total laps Michelle ran, we need to add up the number of laps she ran on each day.
On Monday and Tuesday, she ran 3 1/2 laps each day. This means she ran a total of 3 1/2 + 3 1/2 = 7 laps on those two days.
On Wednesday and Thursday, she ran 2 3/4 laps each day. This means she ran a total of 2 3/4 + 2 3/4 = 5 1/2 laps on those two days.
To find the total laps she ran, we add up the laps from each day: 7 + 5 1/2 = 12 1/2 laps.
