Answer:
0.4 minutes per centimeter
Step-by-step explanation:
We measure pace in units such as hours per mile or seconds per meter. A snail that crawls 5 centimeters in 2 minutes has a pace of 0.4 minutes per centimeter.
To solve this problem, we are going to set up an equation. However, first we need to convert the percentages to decimals by dividing by 100.
15% = 0.15 , 7.5% = 0.075
Now, we should substitute in our given information into our equation and let our unknown value be equal to the variable x.
0.15(500) = 0.075x
Then, we should simplify our equation by multiplying together the two factors on the left side of the equation.
75 = 0.075x
Finally, we should divide both sides of the equation by 0.075 to get the variable x alone.
x = 1000
Therefore, your answer is 1000.
Hope this helps!
The recursive formula 
means that the next term in the sequence is 5 more than the previous one.
So, we know that we start from
