an airplane files 867 miles with a constant speed of 612 mph and then another 1984 miles with a constant speed of 744 mph what i

seraphim [82]

The average speed is the ratio of the total distance to the total time. Then the average speed of the airplane will be 698.19 miles per hour.

<h3>What is speed?</h3>

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

An airplane files 867 miles with a constant speed of 612 mph and then another 1984 miles with a constant speed of 744 mph.

Then time taken for the first trip will be

t₁ = 867 / 612

t₁ = 1.4167 hours

Then time taken for the second trip will be

t₂ = 1984 / 744

t₂ = 2.6667 hours

Then the average speed is the ratio of the total distance to the total time.

The total distance will be

Total distance = 867 + 1984

Total distance = 2851 miles

The total time will be

Total distance = 1.4167 + 2.6667

Total distance = 4.0834 hours

Then the average speed will be

Average speed = 2851 / 4.0834

Average speed = 698.19 mi/h

A bank loaned out $37,500, part of it at the rate of 11% annual interest, and the rest at 9% annual interest. The total interest

kondaur [170]

Answer:

The Loan amount at 11 % interest rate is $ 18,500 And

The Loan amount at 9 % interest rate is $ 19,000

Step-by-step explanation:

Given as :

Let The loan given at interest rate of 11 % annual = $ x

And The loan given at interest rate of 9 % annual = ($37,500 - $ x)

Total interest fro both loan = $3745

I.e CI 1 + CI 2 = $3745

Now, From compound interest method :

$Amount= Principal\times (1 + \frac{Rate}{100})^{Time}$

$A 1 = $ 1\times (1 + \frac{11}{100})^{1}$

Or, A 1 = $ 1.11 x

<u>Similarly</u>

$A 2 = ($37,500 -x ) \times (1 + \frac{9}{100})^{1}$

Or, A 2 = 1.09 × ($37,500 - $ x)

∵ Compound Interest = Amount - principal

Or, $ 3745 = CI 1 + CI 2

Or, $ 3745 = ($ 1.11 x - $ x) + ( 1.09 × ($37,500 - $ x) - ($37,500 - $ x) )

Or, $ 3745 = $ .11 x+ ($37,500 - $ x) ( .09 )

Or, $ 3745 = $ .02 x + $ 3375

or, 0.02 x = $ 3745 - $ 3375

∴ x = $ $\frac{370}{.02}$

SO, x = $ 18,500

And $ 37500 - x = $ 19,000

Hence The Loan amount at 11 % interest rate is $ 18,500 And

The Loan amount at 9 % interest rate is $ 19,000 Answer
