4miles per hour how many feet in 40 minutes can you explain how to do it pls

14080 ft

Step-by-step explanation:

You want to convert 4 mph to ft/min and then mult. the result by 40 minutes:

4 mph       5280 ft          1 hr

* * = 352 ft/min

     1          1 mile            60 min

Now multiply this rate (speed) by 40 minutes:

352 ft      40 min

* = 14080 ft (answer)

  min            1

This would be the same as 2 2/3 miles (in 40 min)

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
