Answer:
30 mins = 0.5 hours
4.5 miles/0.5 hours = your answer
Step-by-step explanation:
M a t h w a y will help you my friend!
I was struggling with math and using it got me get back on track :)
If y varies directly with x, means that they can be modeled by a linear equation, lets choose a line with 0 y intercept, that is:
y = mx + b
y = mx
where m is the slope of the line, now we plug in the data we have:
y = mx
20/3 = m(30)
solving for m:
m = (20/3)(1/30)
m = 20/90
m = 2/9
so the line equation, or function modeling the y and x relationship is:
y = (2/9)x
Answer:
D
Step-by-step explanation:
The lines are parallel, this means that they will never meet.
Well 88.5 +88.5+56.2+56.2= 289.4 meters in perimeter
