Final answer:
After calculating the distance of the completed laps by the student, we subtracted this from the total race distance to find the remaining miles. Then we divided the remaining miles by the length of one lap to find out how many more laps need to be completed, which in this case is 200 laps.
Step-by-step explanation:
The question involves a simple calculation to determine the number of laps remaining in a car race. Initially, we should understand that conversion of track laps to a distance generally involves multiplying the number of laps by the length of a single lap. In this instance, 50 laps of 2 miles each have already been completed, which equals 100 miles. Given that the total race distance is 500 miles, we can find the remaining distance by subtracting the completed distance from the total distance: 500 miles - 100 miles = 400 miles remaining.
Now, to find the number of laps left, we divide the remaining distance by the length of one lap: 400 miles ÷ 2 miles/lap = 200 laps remaining.
