If ( s )stands for speed and later in the question it says that the car was going 55 miles per hour you will replace the s in the equation with the number 55.
55=4.74d
Now you need to find ( d )
If you look at this equation another way you will see that what it’s saying is 4.74 x ? Is 55
Because d replaces the question mark
So 55 divided by 4.74 is 11.603 which is the answer
You can set up a proportion that looks like 3/7 = x/21. X being the number that you are trying to find. Seven goes into 21 three times. So multiply 3 also by that 3 to get 9. So three sevenths of twenty-one is 9.
Thanks for the free points! Have a fantastic day!
