Amy drives 300 miles from London to Newcastle.
WARRIOR [948]

Amy's average speed during her whole journey from London to Newcastle (300 miles) was 51.422 miles per hour.

<h3>How to calculate the average speed?</h3>

This is calculated by taking the total distance and dividing it into the total time.

<h3>What was Amy's average speed?</h3>

First part of ther journey: 165 miles at 60mph, which is equal to 2.75 hours

  • Time: distance/speed
  • Time: 165 miles/ 60 mph= 2.75 hours

Second part of her journey: 135 miles in 3.083 hours (3 hours and 5 minutes)

  • Total distance: 300 miles
  • Total time: 2.75 hours + 3.084 = 5.834

Average speed: 300 miles / 5.834 = 51.422 miles per hour

Write a function describing the relationship of the given variables.
Oliga [24]

Answer:

The function describing the relationship of V and t is V = 3t²

Step-by-step explanation:

* Lets explain the meaning of direct variation

- The direct variation is a mathematical relationship between two

  variables that can be expressed by an equation in which one

  variable is equal to a constant times the other

- If Y is in direct variation with x (y ∝ x), then y = kx, where k is the

 constant of variation

* Now lets solve the problem

# V is varies directly with the square  of t

- Change the statement above to a mathematical relation

∴ V ∝ t²

- Chang the relation to a function by using a constant k

∴ V = kt²

- To find the value of the constant of variation k substitute V and t

 by the given values

∵ t = 6 when V = 108

∵ V = kt²

∴ 108 = k(6)² ⇒ simplify the power 2

∴ 108 = 36k ⇒ divide both sides by 36 to find the value of k

∴ 3 = k

- The value of the constant of variation is 3

∴ The function describing the relationship of V and t is V = 3t²

About how many pounds of coffee will you need to make 600 medium cups of coffee?
Veronika [31]

Answer:

A. 10

Step-by-step explanation:

I found a website that explains that you need 8.3 grams of coffee to make one 5-fl oz cup of coffee.

To make 600 cups, you need 600 * 8.3 g = 4980 g

Now we convert 4980 g to lb.

1 lb = 454 g

4980 g * (1 lb)/(454 g) = 11 lb

The closest answer is A. 10

Answer: A. 10
