Explanation:

The difference between the maximum amount a person is willing to pay for a given quantity of a good and the amount actually paid for that quantity is known as consumer surplus. On a supply and demand curve, it is the area between the equilibrium price and the demand curve. For example, if you would pay 76 dollars for a cup of tea but can buy it 50 dollars, your consumer surplus is 26 dollars

Light travels at approximately 186,282 miles per second (299,792 km per second). Therefore, a light shining from the surface of Mars would take the following amount of time to reach Earth (or vice versa): Closest possible approach: 182 seconds, or 3.03 minutes. Closest recorded approach: 187 seconds, or 3.11 minutes.

Explanation:

  km               light years

54,600,0005.7712 x 10-6

54,700,0005.7818 x 10-6

54,800,0005.7924 x 10-6

54,900,0005.8029 x 10-6

So 54,600,000 km is equal to 5.7712245538e-6 light years.

Hope this helps have a wonderful day!!
