Sally and molly are 12 miles away from each other. Sally runs 5 mph towards Molly, and Molly walks 3 mph towards Sally. How long

ololo11 [35]

Answer:

The time it will take them to meet each other is 1 hour and 30 minutes.

Step-by-step explanation:

Given:

Sally and molly are 12 miles away from each other.

Sally runs 5 mph towards Molly, and Molly walks 3 mph towards Sally.

Now, to find the time it will take them to meet each other.

Let the time be $x.$

Total distance = 12 miles.

Now, find the distance by putting formula:

Distance = speed × time.

Distance Sally runs towards Molly (D1) = $5\times x=5x.$

Distance Molly walks towards Sally (D2) = $3\times x=3x.$

Now, to get the time:

Total distance = D1 + D2.

$12=5x+3x$

$12=8x$

Dividing both sides by 8 we get:

$\frac{3}{2} =x$

$x=\frac{3}{2}$

$x=1\frac{1}{2}$

The time = 1 and 1/2 hour.

That is 1hour and 30 minutes.

Therefore, the time it will take them to meet each other is 1 hour and 30 minutes.

2 cups of low fat yogurt and and 3 bananas contain 650 calories, 4 cups of low-fat yogurt and 2 bananas contain 900 calories. Ho

LenKa [72]

Answer:

A cup of yogurt has 175 calories.

Step-by-step explanation:

We can solve for the amount of calories in one cup of yogurt and in one banana by setting up and solving a system of equations. Given the information in the problem '2 cups of yogurt and 3 bananas is 650 calories' and '4 cups of yogurt and 2 bananas is 900 calories' we can set up two equations:

2y + 3b = 650 and 4y + 2b = 900, where 'y' is the cups of yogurt and 'b' is the number of bananas.

Using elimination, we can multiply the first equation by a factor of '-2' and then add the equations together to solve for the remaining variable:

-2(2y + 3b = 650) = -4y - 6b = -1300

-4y - 6b = -1300

+ 4y + 2b = 900

-4b = -400, or b = 100, so each banana has 100 calories, if each banana has 100 calories: 4y + 2(100) = 900 or 4y = 700 or y = 175. So, each cup of yogurt has 175 calories.
