The estimate to 4 x 979 is 4 x 1,000. The answer is 3,916
If she runs 7 miles every hour and runs a total of 11.2 miles, we can set this up as:
Where x represents the # of hours she ran for. Let's solve for x:
So, she ran for a total of 1.6 hours.
The answer would be .430
in a decimal point
The width of the rectangle is 21.7
If area is equal to length multiplied by the width (A=LW) that would mean all we have to do to find the width of the rectangle is to divide the length (19.2) from the total area (416.64).
416.64/19.2=21.7
Hope this helped! :D
