Final answer:
Mayumi rides her bike for 4 complete laps. The total distance of 3 miles is divided by the distance per lap of 2/3 miles, which gives a result of 4.5. We round down to 4 because it's unlikely she would stop halfway through a lap.
Step-by-step explanation:
Mayumi's park lap is a distance of 2/3 miles. She rides for a total distance of 3 miles. To determine how many laps she rides, we need to divide the total distance she rides by the distance per lap. This gives us 3 ÷ (2/3) = 4.5 laps. However, since it's unlikely she would stop halfway through a lap, we can round this number down to 4 laps. Therefore, Mayumi rides 4 complete laps.
