The sea turtle's speed is
[tex]v_{t} = (27 \, \frac{km}{h} )*(1000 \, \frac{m}{km} )*( \frac{1}{60} \, \frac{h}{min} ) = 450 \, \frac{m}{min} [/tex]
The girl's speed is
[tex]v_{g} = (14 \, \frac{dm}{s} )*( \frac{1}{10} \, \frac{m}{dm} )*(60 \, \frac{s}{min} ) = 84 \, \frac{m}{min} [/tex]
The ratio of the turtle's speed to that of the girl is
[tex] \frac{v_{t}}{v_{g}} = \frac{450}{84} =5.357[/tex]
Answer: 5.36 faster (nearest hundredth)
