A flight averages 460 mph. The return flight averages 500 mph due to tailwind. The total flying time is 4.8 hours how long is ea
Nesterboy [21]

 

We know that time is distance over velocity, that is:

time = distance / velocity

t = d / v

 

Now from the given:

d / 460 + d / 500 = 4.8

Now we can find for d:

d = 4.8 / [1/460 + 1/500]

d = 1150 miles

 

So the time of each flight is:

flight = 1150 / 460 = 2.5 hours

<span>return flight = 1150 / 500 = 2.3 hours</span>

EastWind [94]

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Principal (P)= $2,500

Interest rate= 4%

Number of periods= 2 years

<u>First, we will determine the interest earned using the simple interest formula:</u>

I= P*r*t

I= 2,500*0.04*2

I=$200

<u>Now, using the compound interest formula:</u>

I= [P*(1 + r)^t] - P

r= 0.04/2= 0.02 (semi annual interest rate)

t=2*2= 4 semesters

I= [2,500*(1.02^4)] - 2,500

I= $206.08
