factors:
1609 m/mi
3600 s/h
1000 m/km
24 hr/d
=======================
(.9mi/.5h) = 1.8 mi/h
===========================
now
(1.8mi/h)(1609m/mi)(1h/3600s)
= (1.8*1609/3600) m/s
====================
(1.8*1609/3600)m/s (1km/1000m)(3600*24 s/d)
= 1.8*1.609*24 km/d
1609 m/mi
3600 s/h
1000 m/km
24 hr/d
=======================
(.9mi/.5h) = 1.8 mi/h
===========================
now
(1.8mi/h)(1609m/mi)(1h/3600s)
= (1.8*1609/3600) m/s
====================
(1.8*1609/3600)m/s (1km/1000m)(3600*24 s/d)
= 1.8*1.609*24 km/d
