One of the fastest recorded speeds of a turtle while swimming is 9 m/s. Approximately, what is this speed in kilometers per hour? [1 kilometer = 1,000 meters] [1 hour = 60 minutes = 3,600 seconds]
32.4 km/h
2.5 km/h
6.48 km/h
150 km/h

Answer 1

The correct option is: 32.4 km/h

Explanation:

The fastest recorded speed of a turtle while swimming is 9 m/s.

Now, 9 m/s
`=((9)meters)/((1)second)`

1 kilometer= 1000 meter

So, 1 meter
`= (1)/(1000)=0.001` kilometer

and 9 meters
`=(9*0.001)kilometer = 0.009` kilometer

Now, 1 hour = 3600 seconds

So, 1 second
`=(1)/(3600)hour`

Thus, we will get.........

`((9)meters)/((1)second)=((0.009)/((1)/(3600))) kilometer/hour =(0.009*3600)=32.4 km/h`

So, the speed of the turtle will be 32.4 km/h.
