If the amounts of rainfall in an area over a month are 1.7", 2.2", 0.5", 0.72",
and 1.1", what is the mean amount of rainfall in the area for the month?*

1.244"

Step-by-step explanation:

The mean is given by dividing the sum of the given numbers by the frequency. In this case, the frequency is 5 since we're given 5 rainfall data. The sum of the respective rainfall is equivalent to 1.7"+2.2"+0.5"+0.72"+1.1"=6.22"

Now dividing the above sum by frequency yields mean as follows

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
