Acoach wants to find out the speed of the runners on a track team. tell what simple equipment the coach needs in order to do this and explain how it should be done

The easiest way to measure speed of runners would be to measure the time it takes for a runner to finish a track with a fixed distance. One can use a stopwatch in order to record the time it takes for the runner to run a lap in the track. 

Yes Alice needs to file taxes because her total income was more than $12,00 (the federal minimum for single taxpayers to file taxes).

She will need both of her W2 forms and a 1040EZ form since she will not have enough deductions to itemize her taxes.

Deadline is April 15 (tax Day).

I would recommend she file her taxes online with a tax company like HR Block.
