A sea turtle swims at a speed of 27 kilometers per hour. A girl swims 14 decimeters per second. 1 m = 10 dm 1000 m = 1 km How mu

insens350 [35]

The sea turtle's speed is
$v_{t} = (27 \, \frac{km}{h} )*(1000 \, \frac{m}{km} )*( \frac{1}{60} \, \frac{h}{min} ) = 450 \, \frac{m}{min}$

The girl's speed is
$v_{g} = (14 \, \frac{dm}{s} )*( \frac{1}{10} \, \frac{m}{dm} )*(60 \, \frac{s}{min} ) = 84 \, \frac{m}{min}$

The ratio of the turtle's speed to that of the girl is
$\frac{v_{t}}{v_{g}} = \frac{450}{84} =5.357$

Answer: 5.36 faster (nearest hundredth)
