46.6 km/hr

Work Step by Step

$\frac{0.510in}{ms}\times\frac{2.54cm}{1in}\times\frac{1\times10^{-2}m}{1cm}\times\frac{1km}{1000m}\times\frac{1ms}{1\times10^{-3}s}\times\frac{60s}{1min}\times\frac{60min}{1hr}=46.6$ km/hr Estimate $0.5\times2.5=1.25$ $1.25\times0.01\approx0.01$ $0.01\times60\times60=36$
