You never gave the speed of the blue train.
The path to collision is equal to 1½ circles.
1.5 x 210 meters
= 315 meters
I'm going to arbitrarily guess the speed of the blue train is 15 meters per minute. They are therefore approaching each other at a combined rate of 35 meters per minute.
315 / 35 = 9 minutes
Answer:
9 minutes
<h2>Problem Solving</h2>
Recipe A makes 5 dinner rolls using 1 c of flour. Recipe B makes 24 rolls using 7 1/2 c of flour. which recipe requires the most flour per roll
- To know which recipe requires the most flour per roll, let's convert fraction to decimal.
before that let's convert the recipe B from mixed fraction to decimal then, the total is the numerator and make 24 as the denominator.
How do we convert fraction to decimal?
- Divide the numerator by the denominator.
- Then, add the whole number. ( if it is mixed fraction)
Recipe B
Recipe B
Recipe A
Recipe A
Recipe B is great than Recipe A
Therefore, Recipe B requires the most flour per roll.

Answer:
<u>f(x) = 50 + 25(x - 1)</u>
Step-by-step explanation:
Let's write an equation to represent the function that will allow Damon to calculate the cost of his video game membership service:
Lifetime membership fee = $ 50
First video game is free
Then any video game purchased after = $ 25.
Let x to represent the total cost of the video game membership service, in consequence we can write the equation this way:
<u>f(x) = 50 + 25(x - 1)</u>
- If x = 1, then f(1) = 50 + 0 = 50
- If x = 2, then f(2) = 50 + 25 = 75
- If x = 5, then f(5) = 50 + 100 = 150
