Answer:
1 + 5(77 - s) = 31
Step-by-step explanation:
Solve for s:
![-s+77=6\qquad\text{subtract 77 from both sides}\\\\-s=-71\qquad\text{change the signs}\\\\s=71](https://tex.z-dn.net/?f=-s%2B77%3D6%5Cqquad%5Ctext%7Bsubtract%2077%20from%20both%20sides%7D%5C%5C%5C%5C-s%3D-71%5Cqquad%5Ctext%7Bchange%20the%20signs%7D%5C%5C%5C%5Cs%3D71)
Put the value of <em>s</em> to the expression 1 + 5(77 -s):
![1+5(77-71)](https://tex.z-dn.net/?f=1%2B5%2877-71%29)
Use PEMDAS:
P Parentheses first
E Exponents (ie Powers and Square Roots, etc.)
MD Multiplication and Division (left-to-right)
AS Addition and Subtraction (left-to-right)
![=1+5(6)=1+30=31](https://tex.z-dn.net/?f=%3D1%2B5%286%29%3D1%2B30%3D31)
The answer you already have selected in the image is correct. Even eyeballing it, you can see that the smaller shape fits into the larger shape 4 times.
10/4 is 2.5. The snail travels 2.5 cms ever min. So 24/2.5 is 9.6 so the snail takes 9 mins and 36 seconds.
