#### Answer

$\Delta x = 1.8\times10^{-37}m$
This value is negligible.

#### Work Step by Step

$\Delta x\Delta p$ = $\frac{h}{4π}$
Or $\Delta x.m\Delta v$ = $\frac{h}{4π}$
$\Delta x = \frac{h}{4π.m.\Delta v}$
h = $6.626\times10^{-34}Js$
m = 650 kg
$\Delta v$ = 1 mile/hr = 1609.34 m/3600s
$\Delta x = \frac{6.626\times10^{-34}Js}{4π\times650 kg\times\frac{1609.34m}{3600s}}$ = $1.8\times10^{-37}m$
