2 planes fly in opposite directions. One travels 475 mi/h and the other 525 mi/h . How long will it take before they are 6,000 m

pychu [463]

The speed at which they are moving apart = 475 + 525 = 1000 mi/h

Time = distance / speed
= 6000 / 1000 = 6 hours

The answer is 6 hours.

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

7(2x - 5) = 21

Step 2: Solve for x

Distribute 7: 2x - 5 = 3
Isolate x term: 2x = 8
Isolate x: x = 4

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x: 7(2(4) - 5) = 21
Multiply: 7(8 - 5) = 21
Subtract: 7(3) = 21
Multiply: 21 = 21

Here we see that 21 does indeed equal 21.

∴ x = 4 is the solution to the equation.

Mindy left at 8 a.M. And will arrive at 1 p.M.; jelly left at 8 a.M. And will arrive at 2 p.M. How many miles is the trip if Kel

uysha [10]

Answer:

300 miles

Step-by-step explanation:

The distance equation is D = RT

Where

D is the distance

R is the rate

T is the time

Mindy

8 am to 1 pm = 5 hours

Kelly

8 am to 2 pm = 6 hours

Kelly's rate is 10 mph SLOWER than mindy, so if we let Mindy's rate be "m", so Kelly's rate will be " m - 10 "

Now using the distance equation, we can write:

Mindy >>> D = RT >>> D = 5m

Kelly >>> D = RT >>> D = 6(m-10) >>> D = 6m - 60

Since both the distances are equal, we can write:

5m = 6m - 60

m = 60

We want the distance, we know:

D = 5m

D = 5(60)

D = 300 miles

The distance is 300 miles
