A school bus drove at a velocity of 23.04km/m for 18 minutes. What distance did the bus travel?

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.

You are driving to the grocery store at 20 m/s. you are 110m from an intersection when the traffic light turns red. assume that your reaction time is 0.50s and that your car brakes with constant acceleration. how far are you from the intersection when you begin to apply the brakes? what acceleration will bring you to rest right at the intersection? how long does it take you to stop after the light changes? the known values: vi=20m/s xi=110m t=.50s vf=0m/s xf=0m a=?
