This equation represents slope-intercept for; y = mx + b

m = the slope (slope formula; y2-y1/x2-x1)

b = the y-intercept (point on the graph that lies on the y-axis)

Best of Luck!

A remote control car races down the street at 26 miles per hour. Two hours later a second remote control car races straight down

Neporo4naja [7]

Answer:

4 hours

Step-by-step explanation:

Given

Car 1:

$Speed = 26mph$

$Time = h$

Car 2:

$Speed = 52mph$

$Time = h - 2$ --- i.e. 2 hours after car 1

Required

Determine the time car 1 will meet car 2

To do this, we calculate the distance of both cars using:

$Distance = Speed * Time$

For Car 1:

$Distance = 26 * h$

$Distance = 26h$

For Car 2:

$x^{2} Distance = 52 * (h - 2)$

Open bracket

$Distance = 52h - 104$

When car 2 meets up with car 1, they are at the same distance.

So:

$26h = 52h - 104$

Collect Like Terms

$26h - 52h = -104$

$-26h = -104$

Solve for h

$h = \frac{-104}{-26}$

$h = 4$

Car 2 will catch car 1; 4 hours from the start
