The school district is considering not having bus stops and just having buses travel at 10 mph constant speed without stopping and having students hop on the moving bus. If we forget about the danger of this idea would it save time? Currently the bus stops 5 times per mile, assume that stops are equal distance apart. Each stop takes approximately 2 minutes. Between stops the bus can accelerate to 30mph. How many seconds would it take for the bus moving at a constant speed of 10mph to complete the route? How many seconds would it take for the bus making 5 stops accelerating to 30mph between each stop? (we are going to assume constant acceleration and the route is just 1 mile long).

Up of elements with the same number of valence electrons. vertical column in the periodic table of elements such as alkali metals or halogens. a horizontal row of elements in the periodic table. this is a characteristic of the elements in the periodic table that shows a pattern. it may increase or decrease across or down the table. periodic trend these are the highly reactive elements located in group 1 of the periodic table. these elements have one electron in their outer energy level which makes them highly reactive with water and halogens. these are the reactive elements located in group 2 of the periodic table. these elements have two electrons in their outer energy level which makes them reactive with water and halogens. alkaline earth metals these are the group 3 or d-block elements. these dense metals with high boiling points can have different oxidation states and all are solid at room temperature with the exception of mercury. transition metals this is the highly reactive family of elements with 7 valence electrons. this is an element with full valence shell, very unreactive. this is a group of elements with few valence electrons that conducts heat and electricity. one of a class of elements having properties intermediate to metals and nonmetals. this is a type of element that has many valence electrons, not a conductor.
