A sea turtle swims at a speed of 27 km per h. A girl swims 14 dm per s. How much faster does the sea turtle swim than the girl in meters per minute? 1 m = 10 dm 1000 m = 1 km

Let us convert both speeds to meters per minute.

The turtle:

27 km / hr

1000 m in a kilometer

60 minutes in an hour

(27*1000) / 60

= 450 m/min

The girl:

14 dm / s

0.1 m in a dm

1/60 minutes in a second

(14*0.1) / (1/60)

= 84 m/min

The turtle is

450 - 84

= 366 m/min faster than the girl
