30 is the correct answer your looking for
A She can run the same distance in a shorter amount of time.
Explanation:
Speed is a physical quantity that expresses the rate of change of distance with time:
Speed = ![\frac{Distance}{time}](https://tex.z-dn.net/?f=%5Cfrac%7BDistance%7D%7Btime%7D)
We can see that speed will increase if the distance covered increases with a decreasing amount of time.
Speed will decrease if the distance decreases with increasing time
Speed will increase if the distance covered stays the same with decreasing time
Speed will reduce if the distance covered stays the same with increasing time.

Answer:
Explanation:Digestive juices secreted by various organs such as salivary glands in the mouth, stomach, liver and pancreas help in the process of digestion of food. Saliva secreted by the salivary glands in the mouth aids in the breakdown of starch present in the food to simple sugar
Answer:
voltage drop
Explanation:
Voltage drop is the decrease of electrical potential along the path of a current flowing in an electrical circuit. Voltage drops in the internal resistance of the source, across conductors, across contacts, and across connectors are undesirable because some of the energy supplied is dissipated.
Furthermore, wires carrying current always have inherent resistance, or impedance, to current flow. Voltage drop is defined as the amount of voltage loss that occurs through all or part of a circuit due to Impedance/resistance.
