Velocity in the direction of crossing the river = 3mph
Velocity in the backward direction = 2mph

Net velocity in forward direction = (3-2)= 1mph

Distance = 6 miles

t = ?

Velocity = Displacement/Time
1 = 6/t
t = 1/6 hr
t = (1/6)×60 min

time = 10 minutes

We know that the sum of all angle measures in a trapezoid is 360* (* means degrees)

Therefore we can construct the equation
(X+28)+(x)+(4x-14)+(4x-14)= 360

Now add like terms

10x = 360

And divide by the coefficient of X (aka 10)

X= 36

Answer:

  • 1) y = 13.5x + 1
  • 2) y = 12x + 4
  • 3) Sam won the race

Step-by-step explanation:

<h3>Part 1</h3>

Sam's car is 1 ft in front of the start line and its speed is 13.5 ft/s.

<u>The distance after x seconds is:</u>

  • y = 13.5x + 1
<h3>Part 2</h3>

Alice's car the speed 12 ft/s and after 3 seconds is 40 ft in front of the start line.

<u>The distance after x seconds is:</u>

  • y = 12(x - 3) + 40 = 12x - 36 + 40 = 12x + 4
<h3>Part 3</h3>

<u>After 15 seconds the distance from the start line is:</u>

  • Sam   ⇒ y = 13.5*15 + 1 = 203.5 ft
  • Alice  ⇒ y = 12*15 + 4 = 184 ft

As we see Sam is further from the start line than Alice
