Step-by-step explanation:
To solve this problem, let's set up our equation to solve for x (time to travel 13 miles).

We use this equation to find x. To solve, we divide 13 by 65 to get our answer.
13 ÷ 65 = 0.2
Our answer: 0.2 hours
Answer: 2.8%
Step-by-step explanation:
Give, In a certain month a family spent $750 on food
In third month the family spent $729 on food .
i.e. Expenditure on food in a certain month = $750
Expenditure on food in third month = $729
Decrease in monthly spending on food = (Expenditure in a certain month )- (Expenditure in third month )
= $750 - $729
= $21
Now , the percentage decrease in the month spent on food will be :

Hence, the percentage decrease in the month spent on food is 2.8%.
