Answer
a) $118.39 in/s$
b) $180.38m/min$
c) $10.82km/h$
Work Step by Step
a) in/s
8.92 min for 1 mi (which is 63360 in)
$1min=60seconds=\frac{63360}{8.92} in$
$\frac{63360}{8.92} in/s=frac{63360}{8.92\times60}$
$\approx 118.3856502242152466$
$=118.39 in/s$
b) m/min
$1mi=1609m for 8.92 min$
$1 min = \frac{1609}{8.92} m$
$\approx180.3811659192825112m$
$=180.38m/min$
c) km/h
$1609m=1.609km=\frac{8.92}{60}h$
$1h=\frac{(1.609\times60}{8.92}km$
$\approx 10.8228699551569507km/h$
$=10.82km/h$
