Now that you have a mean value for each treatment, it’s important to examine the variation around that mean. To do so, calculate the standard deviation for each treatment using the following formula: s=1n−1Σ(xi−x¯)2−−−−−−−−−−−√.

10/60

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
