Two angry children 450 feet apart are headed straight towards each other—one at 15 feet per second and the other at 6 feet per s
sergiy2304 [10]
If the amount of time is x seconds, then 15*x is the amount ran by one child and 6*x is the amount ran for the other child due to that they add 15 or 6 feet for each second. In addition, since they are 450 feet apart, 15x+6x=450=21x. Dividing both sides by 21, we get x=around 21.4 seconds. Since the mother is always between them, when those two meet is when the three meet. Therefore, she runs 20* around 21.4= around 428.57 feet

A recipe for fruit punch requires 1 1/2 quarts of orange juice to make 6 quarts of punch. How many
Bingel [31]

Answer:

\frac{1}{4} quarts of orange juice.

Step-by-step explanation:

Given:

Quarts of orange juice required for 6 quarts of punch = 1\frac{1}{2} =\frac{3}{2}

∴ Quarts of orange juice required for 1 quart of punch = \frac{\frac{3}{2}}{6}=\frac{3}{2}\times \frac{1}{6}=\frac{3}{12}=\frac{1}{4}

Therefore, \frac{1}{4} quarts of orange juice are required for one quart of punch.
