A small plane flew 240 miles in 2 hours.At that rate how long will it take to travel 600 miles?please so me the work
Furkat [3]
So, in 240 miles can be made by 2 hours.
Do this equation:

240 × 2 = 480 / 4 hours.

You cannot do 3 because it won't fit another 240 miles.

Next, subtract the 480 miles from 600 miles.

600 - 480 = 120

Also, if you would've divided by 2 hours.

240 ÷ 2 = 120 / 1 hour

Add the hours.

4 + 1 = 5 hours

It takes 5 hours to travel 600 miles by the small plane.

A 0. 0427 kg racquetball is moving 22. 3 m/s when it strikes a stationary box. The ball bounces back at 11. 5 m/s, while the box

To solve the question we must know about the conservation of momentum.

<h2>Conservation of Momentum</h2>

According to the law of conservation of momentum, when two bodies collide with each other then their momentum is conserved if no external force acts on the system. therefore, the combined momentum of the two objects before collision will be equal to the combined momentum of the two objects after the collision.

the momentum of the two objects before the collision

                       = momentum of the two objects after the collision

The mass of the box is 0.30141 kg.

<h2>Explanation</h2>

Given to us

  • Mass of racquetball, m = 0.0427 kg,
  • Velocity of racquetball before Collision,  \bold{u_1} = 22.3 m/s,
  • Velocity of box before Collision,\bold{ u_2}  = 0 m/s,
  • Velocity of racquetball after Collision, \bold{v_1} = 11.5 m/s,
  • Velocity of box after Collision, \bold{v_2} = 1.53 m/s,

<h3>Assumption</h3>

Let the mass of the box be M.

<h3>Conservation Of Momentum</h3>

Momentum before collision = Momentum after collision

mu_1 + Mu_2 = mv_1 + Mv_2

given, the box was stationary before the collision,

mu_1 + Mu_2 = mv_1 + Mv_2\\\\&#10;mu_1 + 0 = mv_1 + Mv_2\\\\&#10;mu_1  - mv_1 = Mv_2\\\\&#10;M= \dfrac{mu_1  - mv_1}{v_2}

Substituting the values,

M= \dfrac{mu_1  - mv_1}{v_2}\\\\&#10;M = \dfrac{(0.0427 \times 22.3)  - (0.0427\times 11.5)}{1.53}\\\\&#10;M = 0.30141\ kg

Hence, the mass of the box is 0.30141 kg.

Sergeu [11.5K]

Answer:

the number of chocolates remains unsold is 5,472

Step-by-step explanation:

The computation of the number of chocolates remains unsold is given below:

= (Total boxes - sold boxes) × number of chocolates in each box

= (295 - 67) × 24

= 228 × 24

= 5,472 chocolates

hence, the number of chocolates remains unsold is 5,472

Answer:

  C.  96 ft³

Step-by-step explanation:

The area of the triangular base is ...

  A = 1/2bh

  A = 1/2(6 ft)(8 ft) = 24 ft²

Then the volume is ...

  V = 1/3Bh . . . . . where B is the base area and h is the height

  V = 1/3(24 ft²)(12 ft) = 96 ft³ . . . . volume of pyramid
