Light travels at 186,000 miles per second. Light takes about 11⁄3 seconds to travel from the earth to the moon. Calculate the di
san4es73 [151]

Answer:

682,000 miles

Step-by-step explanation:

Using the ratio of 186,000 miles per second:

\frac{miles}{second}=\frac{186,000}{1}

we can set up a proportion (equivalent ratios) to find the distance, in miles, from the earth to the moon

\frac{186,000}{1}=\frac{x}{\frac{11}{3}} where 'x' is the number of miles between the earth and the moon

Cross-multiply:  x = 186,000*\frac{11}{3}

Solve for x = 682,000 miles

Answer:

  • x = 8.5

Step-by-step explanation:

<u>Since T is midpoint, ST and TU have equal length:</u>

  • ST = TU

<u>Substitute the values and solve for x:</u>

  • 6x - 8 = 4x + 9
  • 6x - 4x = 9 + 8
  • 2x = 17
  • x = 17/2
  • x = 8.5
