Mr. Nesbit realized that the bell was about to ring and he was going to be late. So he ran the last 20 meters to his classroom in 4 seconds. What was Mr. Nesbit's
speed? *

5 meters per second

most probably 5m/s

since , speed = distance / time

=> 20 / 4

=> 5m/s

hope that helps uhh!! :)

answer: i believe c. is the answer sorry if i am wrong

step-by-step explanation:

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
