Question

An alligator swims at an average rate of 3. 218 m/sec. How fast does it swim in mi/hr?

Answer 1

Answer: 7.2 mi/hr

Explanation:

You need to multiply by conversion factors that cancel out:

`3. 218 (m)/(sec) =3. 218 (m)/(sec) * (1 mi.)/(1609.34 m)` >see how m cancels now you are in mi/s

`=(.00199958 mi)/(sec) *(60 sec)/(1 min)` >now in mi/min

`=(.119974 mi)/(min) * (60 min)/(1 hr)` > now in mi/hr

`=7.2 (mi)/(hr)`

Answer 2

6.9747674, to the ratio
