Please solve the question and give correct answer with explanation so that i can understand it​
denis-greek [22]

Answer:

  • Yes

Step-by-step explanation:

Let the speed of the car is c and speed of the plane is p.

<h3>We are given:</h3>

The speed of the plane is 7 times the speed of the car

  • p = 7c

The distance traveled is

  • d = 315 km

The time difference to travel this same distance is 3 hours.

<h3>We know that:</h3>
  • d = ts, where d- distance, t- time, s - speed

Find the time for car and plane and their difference.

<h3>Car</h3>
  • t = d/s = 315/c
<h3 /><h3>Plane</h3>
  • t = d/s = 315/p = 315/(7c) = 35/c
<h3 /><h3>The difference</h3>
  • 315/c - 45/c = 3

<u>Solve it for c:</u>

  • (315 - 45)/c = 3
  • 270/c = 3
  • c = 270/3
  • c = 90 km/h

Now find the speed of plane:

  • p = 7c = 7*90 = 630 km/h

As we see, Jenny is right

What is the justification for each step in the solution of the equation?
Marrrta [24]
4(4x + 6) - 7 = 77 - 4x......distribute thru the parenthesis
16x + 24 - 7 = 77 - 4x ...simplify
16x + 17 = 77 - 4x ...addition property of equality....add 4x to both sides
16x + 4x + 17 = 77 ...subtraction property ...subtract 17 from both sides
16x + 4x = 77 - 17...combine like terms
20x = 60 ....division property....divide both sides by 20
x = 60/20
x = 3
