Question

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 much faster does the sea turtle swim than the girl in meters per minute?

Answer in meter per minute

Answer 1

~~~~~~~~~~The answer is 366 m/min~~~~~~~~~~~~~~~~~~ First, convert the turtles speed to meters per minute. 27 km/h * 1000 m/km = 27000 m/h / 60 min/h = 450 m/min Now convert the girls speed to meters per minute. 14 dm/s / 10 dm/m * 60 s/min = 84 m/min Now subtract the girl's speed from the turtle's speed. 450 m/min = 84 m/min = 366 m/min

Answer 2

We need to convert both speeds into meters per minute.

27 km/h * (1000 m)/(1 h) * (1 h)/(60 min) = 450 m/min

14 dm/s * (1 m)/(10 dm) * (60 s)/(1 min) = 84 m/min

The difference in speeds is 450 m/min - 84 m/min = 366 m/min
