Caden exercises daily by walking on a treadmill. He sets the machine so that he will walk at a steady rate of 3.6 miles per hour. A. If t represents time in hours and d represents distance in miles write an equation that models the relationship between these variables

B. Use your equation to calculate the distance Caden will walk in 3 of an hour .

C. Use your equation to calculate how long it will take for Caden to walk 4.32 miles

(i have to write sumn for this part)​

a) d = 3.6t

b) 10.8 miles

c) 1.2 hours

Step-by-step explanation:

For part a:

Slope of a line: y = mx + b

In this case, the equation would be: d = mt,

where m represents the speed Caden is walking at.

Note: b = 0 in this case because when Caden starts walking on the treadmill, he hasn't really covered any distance yet.

Therefore, plugging in a speed of 3.6 miles per hour, the equation is:

d = 3.6t

For part b:

This is a simple instance of plugging in 3 hours for our t value.

Therefore, d = 3.6 (3)

d = 10.8 miles

For part c:

In this case, we are given that d = 4.32 miles.

Therefore, 4.32 = 3.6t

Dividing both sides by 3.6, we get

t = 1.2 hours

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
