Answer:

  • y = 10x

Step-by-step explanation:

  • Number of hours worked = x
  • Total earning = y
  • Earning per hour = $10

<u>The proportional relationship formula for this situation is:</u>

  • y = 10x

We just substituted k with 10 to represent hourly earning.

  • He earns per hour=10

Let hours be x

  • He earns in 1 h=10x=10(1)=10
  • He earns in 2h=10(2)=20

Hence the expression is

\\ \sf\longmapsto y=10x

Beth left school driving toward the lake one hour before tim. tim drove in the opposite direction going 6 mph slower than beth f

Beth's speed was 60 mph.

<h3>What is speed?</h3>
  • The speed (commonly referred to as v) of an object in everyday use and kinematics is the magnitude of the change in its position over time or the magnitude of the change in its position per unit of time; it is thus a scalar quantity.
  • The distance traveled by an object in a time interval is divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero.
  • Velocity is not the same as speed.

To find what was Beth's speed:

Beth's data:

  • time = 2 hrs; rate = r mph; distance = r×t = 2r miles

Tim's data:

  • time = 1 hr; rate = r-6 mph; distance = r-6 miles

Equation:

  • distance + distance = 174 miles

So,

  • 2r + r - 6 = 174
  • 3r - 6 = 174
  • 3r = 180
  • r = 60 mph (Beth's rate)
  • r-6 = 54 mph (Tims's rate)

Therefore, Beth's speed was 60 mph.
