The first lap of an auto race is 2500 m. this is 10% of the total race distance. the answer is 10. what is the question?

I think the question would be, In an auto race which is 25,000 meters, there are ten laps covered. How long is the first lap, and what is the percentage of the lap to the total distance? 
So that the calculation will be
 25000/ 10 = 2500 m (Length of the first lap)
the percentage of the lap to the total distance
(2500/25000) × 100 = 10 %

All points to the left of zero on a horizontal number line are negative. a number line is a picture of a graduated straight line that serves as abstraction for real numbers. this number line can be extended to the left to represent numbers which are smaller than 0. such numbers are called negative numbersmark me brainliest
