Answer

(a) $6.15\times 10^{-3}~s$ (b) $27,210~m$ (c) $31.1~m/s$ (d) $0.072~m/s$

Work Step by Step

(a) $6.15~ms = 6.15\times 10^{-3}~s$ (b) $27.21~km = 27,210~m$ (c) $(112~km/h)(\frac{1~h}{3600~s})(\frac{1000~m}{1~km}) = 31.1~m/s$ (d) $(72~\mu~m/ms)(\frac{1~m}{10^6~\mu~m})(\frac{1000~ms}{1~s}) = 0.072~m/s$
