You are measuring the time that it takes for a NASCAR driver to travel the length of a straightaway

in order to estimate their average speed, $.$ If you estimate that the straightaway is $\backslash$Delta $=180\backslash$pm $10$ m

long and you measure the time it takes for the driver$$s car to traverse the straightaway as $\backslash$Delta $=2\mathrm{.}0\backslash$pm

$0\mathrm{.}5$ s$,$ what is the driver$$s average speed?
