Question

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

Answer 1

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
