A giraffe can run 32 mph. What is the speed in feet per second ?

Answer:

First, make sure to convert the units so they match up the question.
So, convert 32 miles to x feet and an hour to x seconds.
There are 5280 feet in 1 mile. Therefore multiply 32 * 5280 = 168,960.
For hours to seconds- first find how many minutes are in an hour. That would be 60. Then change the minutes to seconds. There are 60 seconds in a minute. So you do 60 * 60 = 3,600.
Now that you have converted the units, you have a ratio of 168,960/3,600. Simplify this ratio to find how many feet per second. To do this, divide.
168,960/ 3,600=46.9333333333
Because there is a repeating decimal, you can round this to whatever place value the question asks you to. for example, if it tells you to round to the hundredths, the answer is 46.93 ft/s. If they tell you to round to the nearest whole number, the answer is 47 ft/s.
