A snowplow has maximum speed of

35

miles per hour on a dry highway. Its maximum speed decreases by
1.3

miles per hour for every inch of snow on the highway. According to this model, at what snow depth will the snowplow be unable to move?The equation used to model this situation is

nothing,

wheres is the maximum speed of the snowplow in miles per hour and d is the snow depth in inches.Step 1

Given, a snowplow has maximum speed of 35 miles per hour on a dry highway. Its maximum speed decreases by 1.3 miles per hour for every inch of snow on the highway.

Here, the y-intercept c is 35 and the rate of change (slope) m is -1.3.

Step 2

A linear equation is of the form,

y = mx + c

So the equation that used to model this situation is,

y= -1.3x+35

Step 3

To find the depth that the snowplow wil...
