Answer:
no horse can run 18 miles per second or even 2 miles per second.
Step-by-step explanation:
Time Distance Distance / Time
2hrs 90 miles 90 miles / 2 hrs = 45 miles / hr
3hrs 135 miles 135 miles / 3 hrs = 45 miles / hr
5hrs 225 miles 225 miles / 5 hrs = 45 miles / hr
6hrs 270 miles 270 miles / 6 hrs = 45 miles / hr
Constant of proportionality is 45 miles / hr. This is the same for the four values. The unit rate is also 45 miles / hr.
Let us assume the Distance , d is directly proportional to Time, t
d α t
d = kt
Constant of proportionality is k which is D/T
d = 45t
Answer:
Option 2 - 
is the slope of the equation.
Step-by-step explanation:
Given : Equation 
To find : What is the slope of the line represented by the equation ?
Solution :
The slope form of line is 
Equation
Take 2x to another side,
Divide 3 both side,
On comparing with general equation,
is the slope of the equation.
Therefore, option 2 is correct.
