A high school athlete runs 1.00 x 10 m in 12.20 s. What is the velocity in m/s and km/h?

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !

Ithink it is a. but i'm not 100 percent sure.

The capital letters and lowercase letters smoothly run together without lifting the pen
