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

Is the open sentence 3z=2z+5 true or false when z=5?<br><br> A. True<br> B. False
inna [77]
Hey there! 

If z = 5 

we replace "z" with "5" 

So, let's test out the problem to see if it is true or false

Problem becomes: 3(5) = 2(5) + 5

Let's work this out

3(5) = 15

Problem becomes: 15 = 2(5) + 5

2(5) = 10

Problem becomes: 15 = 10 + 5

10 + 5 = 15

So, therefore it looks like this statement/ sentence is True!

attashe74 [19]
<h2>The bond will be worth in total after 10 years is =$1,950</h2>

Step-by-step explanation:

Given,

Nora invested $1,500 in at a bond simple interest rate of 3%

here P= $1500 R= 3% and t = 10year

Simple interest(I) = \frac{P\times R \times t }{100}

                           =$ \frac{1500\times 3 \times 10}{100}

                           =$ 450

<h3>The bond will be worth in total after 10 years is = $1,500+ $450</h3><h3>                                                                                      =$1,950</h3>
