Answer:
B
Step-by-step explanation:
Shape: the form of an object
Outline: the line by which a figure or object is defined or bounded
Center: Point that is equal distances from any point of the circle
Spread: the measure of how far the numbers in a data set are away from the mean or the median
The examples of 50,000 written as an exponent are as follows (but not limited to):
500 * 10^2
50 * 10^3
5 * 10^4
0,5 * 10^5
Doublecheck (optional):
500 * 10^2 = 500 * 100 = 50,000
50 * 10^3 = 50 * 1000 = 50,000
5 * 10^4 = 5 * 10000 = 50,000
0,5 * 10^5 = 0,5 * 100000 = 50,000
Note --> As you're writing 'zeroes' , I assume there is a typing mistake and you've given a Quadratic equation in the question

Hence , the roots are 1/2 and -6
The graph attached confirms the same ,
Hope it helps you :)
15 + 20 equals to 35, 60 - 35 equals to 25 so so his total journey is 1 hour
